Opis:: We report on the synthesis, crystal structure determination, and magnetic susceptibility measurements of Eu₃Pd₂Sn₂, EuPd₂Sn₄, and EuPdSn₂. For all three compounds a divalent state of Eu ions was obtained from the fitting of the magnetic susceptibilities. At low temperatures Eu₃Pd₂Sn₂, EuPd₂Sn₄, and EuPdSn₂ order magnetically at 23, 12, and 13 K, respectively.

Opis:: Point-contact spectroscopy measurements have been performed on the $R_3Pd_{20}X_6$ (R = La, Ce; X = Si, Ge) cage compounds. In case of La the characteristic phonon energies have been obtained in agreement with that of the Raman scattering. In $Ce_3Pd_{20}Si_6$ we have observed asymmetric behaviour of dV/dI(V) dependences which was observed in non-Fermi liquid compound. In $Ce_3Pd_{20}Ge_6$ we have observed maxima at crystalline electric field energies, influenced by magnetic field. This is connected with quadrupolar ordering transition.

Opis:: Heat capacity measurements performed on the new ternary compound $YbCu_4Ni$ indicate for this compound strong electronic correlations with possible antiferromagnetic phase transition below 0.5 K. Susceptibility and magnetisation measurements above 2 K show no magnetic ordering.

Opis:: We have prepared a new system of $Gd_{1-x}Ce_xNi_5$ polycrystalline samples with concentrations x =0, 0.2, 0.5, and 0.8 in order to study the influence of different rare-earths substitutions on the ground state connected with spin fluctuations. GdNi₅ is a ferromagnetic compound with $T_{C}=31.8 K$ and CeNi₅ is a well-known spin fluctuation compound without magnetic ordering down to the lowest temperatures. X-ray diffraction study confirms the hexagonal crystal structure and the single phase samples. Magnetic properties (M(T),M(B)) show that an increasing content of Ce depresses the transition temperature, $T_{C}$, down to 4.9 K for x=0.8. The heat capacity measurements confirmed these results.

Opis:: An investigation of the magnetic heat capacity of the heavy-fermion compound $YbCu_4Ni$ up to 0.4 K is presented. The novel compound $LuCu_4Ni,$ isotypic with $YbCu_4Ni$ has been synthesized and characterized, and its heat capacity was measured in order to subtract the lattice contribution from the previously measured heat capacity data of $YbCu_4Ni$.

Opis:: The results on the influence of magnetic field on the electrical resistivity ρ(T) of the heavy fermion $YbCu_4Ni$ in the temperature range 0.4-300 K are presented. We have observed a Kondo-like behaviour below 10 K with a minimum in ρ(T) at about 60 K. An applied magnetic field depresses this behaviour, and a maximum in ρ(T) appears similarly to the maximum observed in heat capacity. The observed electrical magnetoresistance shows negative values in all applied magnetic fields and with increasing temperature its absolute magnitude increases. Moreover, we extended our previous susceptibility measurements up to high temperatures of 1000 K, in order to study possible mixed valence behaviour, which however was not observed.

Opis:: Angular magnetoresistance of the filled skutterudite compound CeOs₄Sb₁₂ has been investigated along the [110] direction. Distinct differences between the angular magnetoresistance data at T = 0.55 K and 4.2 K coincide with a developing of spin-density waves at T ≈ 1.7 K in B = 5 T. Magnetoresistance experiments have been performed on a self-made assembly utilizing a commercial piezoelectric rotator.
