Opis:
Single crystals of TbPdBi, a representative of the group of half-Heusler bismuthides, were studied by means of magnetic susceptibility, heat capacity, electrical resistivity, magnetostriction and thermal expansion measurements. The compound was characterized as an antiferromagnet with the Néel temperature T_{N} ≈5.3 K. Neutron diffraction experiment confirmed the antiferromagnetic ordering and yielded the propagation vector k=(1/2,1/2,1/2). Remarkably, this k vector is in accord with the recently developed theory of antiferromagnetic topological insulators.

Opis:
Single-crystals of LuSb were investigated by means of electrical resistivity and magnetoresistance measurements. The compound was found to exhibit giant magnetoresistance exceeding 3000%, low-temperature resistivity plateau, and Shubnikov-de Haas oscillations. It was characterized as a semimetal with nearly balanced contributions of electron and hole carriers to the magnetotransport properties. The experimental findings, supported by the results of electronic structure calculations, proved that the magnetotransport in LuSb can be described in the scope of 3D multi-band Fermi surface model without topologically non-trivial electronic states.

Opis:
The low-temperature magnetic, thermal and magnetocaloric properties of the half-Heusler compound DyNiSb were studied on polycrystalline samples. The temperature variations of the magnetization and the heat capacity revealed a phase transition from paramagnetic to antiferromagnetic state at the Néel temperature T_{N} = 3.1 K. The compound exhibits normal and inverse magnetocaloric effect with the isothermal magnetic entropy change reaching 5.2 J/(kg K) at 4.8 K for a magnetic field change of 3 T. The estimated refrigerant capacity is about 58 J/kg.

Opis:
High quality single crystals of some representatives of half-Heusler family were grown from Bi-flux. For single crystals characterization, X-ray diffraction and scanning electron microscopy techniques were used. The low-temperature physical properties of the synthesized crystals were determined by means of magnetization, magnetic susceptibility, electrical resistivity and heat capacity measurements. For each compound but LuPtBi, the electrical resistivity varies in a semimetallic manner at high temperatures, and exhibits a metallic character at low temperatures. LuPtBi is metallic in the whole temperature range studied. The bismuthides HoPdBi, LuPdBi, LuPtBi and YPtBi were found superconducting below the critical temperature $T_{c}$ = 0.7, 1.8, 0.9, and 0.96 K, respectively. For the compounds GdPdBi, DyPdBi and HoPdBi, an antiferromagnetic ordering was found to set in below $T_{N}$ = 12.8, 3.7, and 1.9 K, respectively. HoPdBi is thus an intriguing material in which both cooperative phenomena coexist.

Opis:
Titanium and its alloys are one of the most popular metallic materials used in medicine for many years. Their favorable mechanical properties, high corrosion resistance and good biotolerance in an environment of tissues and body fluids, cause that they are widely used as construction material of orthopaedic dental and neurological implants. Their disadvantages are poor tribological properties manifested by high coefficient of friction, scuffing and tendency to formation of adhesive couplings. In many research centers the works on improving the unfavorable tribological properties of titanium alloys are conducted. They rely on the use of modern methods of surface treatment including the thermo-chemical methods (nitriding, carburizing, oxidation) and the synthesis of thin films using PVD and CVD methods. In the presented work the glow discharge oxidation was applied to improve the surface properties of two-phase Ti6Al4V and Ti6Al7Nb titanium alloys. The results include a description of the obtained structure of the surface layer, surface topography, micro-hardness, wear ratio and corrosion resistance. The obtained results indicate changes in the surface layer of the material. The surface hardness was more than doubled and the depth of increased hardness region was up to 85 microns. This, in turn, several times decreased the wear rate of the modified materials while reducing the wear rate of the countersample. At the same time the carried out thermo-chemical treatment did not cause any structural changes in the core material. The oxidation process preferably influenced the corrosion properties of titanium alloys. Both, significant increase in the corrosion potential (approx. 0.36 V), as well as increased polarization resistance were observed. The modified surfaces also retained a high resistance to pitting corrosion.

The compound ThIr₂Si₂ crystallizes with a tetragonal crystal structure of the CaBe₂Ge₂-type (space group P4/nmm). Its low-temperature physical properties were investigated by means of magnetization, electrical resistivity, and heat capacity measurements, performed down to 0.35 K. The experiments revealed bulk superconductivity below $T_{c}$ = 2 K. The obtained data indicate that ThIr₂Si₂ is a weakly-coupled type-II BCS superconductor.

Opis:
Since a few years europium-based intermetallics have been attracting more and more attention due to their intriguing physical properties with anomalous behaviours in magnetically ordered states. Here, we report on the formation and the bulk physical properties of two tetragonal compounds EuCoGe₃ and EuRhGe₃, studied on high-quality single-crystalline specimens. In both materials, the Eu ions are in their divalent state, which gives rise to an antiferromagnetic ordering below $T_{N}$ = 15.4 K and $T_{N}$ = 11.3 K, respectively. In addition, EuCoGe₃ exhibits a successive antiferromagnetic phase transition at T₂ = 13.4 K. Based on some characteristic features in the temperature variations of the magnetic susceptibility, specific heat and electrical resistivity, we suggest that in both germanides an amplitude modulated magnetic structure develops below the respective $T_{N}$, with the Eu magnetic moments directed along the crystallographic [001] axis in EuCoGe₃ and perpendicular to this direction in EuRhGe₃.

We present results of extensive measurements of magnetic susceptibility, electrical resistance, specific heat and thermoelectric power of two series of solid solutions $GdNi_{x}Ga_{4-x}$ and $GdCu_{x}Ga_{4-x}$, for ranges of doping x from 0.6 to 1 and from 1 to 1.5, respectively. All studied phases display the Curie-Weiss behaviour of magnetic susceptibility and antiferromagnetic ordering at temperatures below 23 K. Substitution of gallium with transition metal atoms has strong influence on Néel temperatures of all studied phases, shifting them by few K, depending on x. Metamagnetic-like anomalies are observed for some compositions. Behaviour of the electrical resistivity reveals metallic nature of all samples. Their magnetic ordering is reflected in low-temperature anomalies of the resistivity and the heat capacity.

Opis:
Single crystals of ErPdBi were grown from Bi-flux. The crystal structure of MgAgAs-type was confirmed using X-ray diffraction. Magnetization, magnetic susceptibility, electrical resistance and heat capacity measurements revealed an antiferromagnetic phase transition at $T_{N}$ = 1.2 K. At high temperatures, the electrical resistance has a semiconducting-like character (dR/dT < 0 ). The resistance starts decreasing with decreasing T below 15 K and shows a very sharp drop below $T_{N}$ but remains finite down to 0.4 K. Hence, no obvious evidence of superconductivity was found in the electrical transport data. On the other hand, the real part of AC magnetic susceptibility is negative below $T_{C}$ = 1.6 K and its imaginary component has a clear maximum at this temperature that might be associated with the onset of superconducting state. The electrical resistance revealed Shubnikov-de Haas oscillations in magnetic fields 8-33 T. Their amplitude decreases with increasing T and disappears above 10 K. Cyclotron mass determined from this dependence is 0.21 $m_{e}$.

Opis:
A single-crystalline sample of disordered ferromagnetic U₂NiSi₃ was investigated by means of electrical resistivity measurements under ambient and high hydrostatic pressure. Temperature dependences of the electrical resistivity clearly reveal interplay of the ferromagnetic ordering and quantum interference effects resulting from crystallographic disorder. Electron-electron interaction manifests itself as a $T^{0.5}$ increase in the in-plane and out-of-plane electrical resistivity below 5 K. Weak localization is observed solely in the ab-plane as a linear-in-T contribution to resistivity, which suggests that internal magnetic field does not break the interference of scattered electron waves in ab-plane. Applied hydrostatic pressure does not affect the $T^{0.5}$ electron-electron interaction contribution, however it diminishes the impact of weak localization on the ab-plane resistivity.

Opis:
This work presents studies of the valence band of two Kondo lattice systems: $Ce_2Co_{0.8}Si_{3.2}$, which is paramagnetic with the Kondo temperature $T_{K}$ ≈50 K and $Ce_2RhSi_3$, which is antiferromagnetic below $T_{N}$=4.5 K and exhibits $T_{K}$ ≈9 K. The photoemission spectra, which are obtained with photon energy tuned to Ce 4d-4f resonance, reveal a Kondo peak at the Fermi energy $(E_{F})$, its spin-orbit splitting partner at 0.24 eV and a broad maximum related to Ce $f^0$ final state. The spectra indicate that Kondo peak has a higher intensity for $Ce_2Co_{0.8}Si_{3.2}$. The off-resonance photoemission data reveal that a maximum in the 3d electron density of states is shifted towards $E_{F}$ for $Ce_2Co_{0.8}Si_{3.2}$ as compared to $Ce_2RhSi_3$. Full-potential local-orbital calculations were realized with local spin density approach +U approach for 213 stoichiometry. They show that a higher density of states near $E_{F}$ is observed for $Ce_2CoSi_3$. The calculations also reveal the existing tendencies for antiferromagnetic and ferromagnetic ground states in a case of $Ce_2RhSi_3$ and $Ce_2CoSi_3$, respectively.
