Opis:
Absorption of electromagnetic waves by graphene-magnetic semiconductor multilayered structure has been investigated for the Voight geometry with taking into account the dissipation processes. The possibility of control of electrodynamic properties of the structure by an external magnetic field, changing in number of periods of the structure, chemical potential of the graphene layers and temperature has been shown. Electrodynamics of the structure is also sensitive to polarization of the incident wave. The structure shows to be especially controllable at terahertz frequencies.

Opis:
Electromagnetic waves generated by the Heusler alloy $Ni_{2.14}Mn_{0.81}GaFe_{0.05}$ at structural phase transition was detected in the frequency range of 28-32 GHz. Influence of the kinetics of phase transitions on the nature of the sample millimeter radiation was studied as well. It has been observed that the contribution of the intrinsic radiation increases with increasing of the heating/cooling rate. The possible mechanisms and theory of such effect is discussed. It is shown that the maximum radiation intensity should be emitted in direction perpendicular to the movement of interphase boundary.

Opis:
This work deals with the tube sinking process. The main purpose is to develop a process chain for the manufacturing of ultra-thick-walled tubes with the lowest possible diameter. The base material is a hot extruded tube consisting the aluminium alloy AA6063 with the dimensions 9,9 ×1 mm. The drawing tools include several dies with various exit holes, a drawing bench and a muffle oven to produce ultra-thick-walled tubes with dimensions 5,02…5,03 × 1,54…1,59 mm. The process has been applied successfully. With a double-layered tube, it was possible to reach a low diameter/wall-thickness ratio of 3,3 at tube sinking process. Subsequent pull-out tests showed that by reaching the threshold outer tube diameter value of Ø 5 mm the joining strength increased from 1,3 MPa to 6,2 MPa. It could be observed that the heat treatment reduced the joining strength for the double-layered tubes with diameter of 5 mm, whereupon for the bigger tubes diameter it has no significant influence on the joining strength.

Opis:
The static magnetization of the EuBaCo$\text{}_{2}$O$\text{}_{5.5}$ single crystals was measured from helium to room temperatures for two configurations of the applied field: parallel and perpendicular to the c-axis. The compound is antiferromagnetic from helium temperature to about 210 K. In low temperature region (below 45 K) the antiferromagnetism coexists with a spin-glass-like state. The metamagnetic field-induced phase transition was observed in the antiferromagnetic phase for magnetic field applied perpendicular to the c-axis. The spontaneous phase transition from antiferromagnetic to weak ferromagnetic phase was established to be of the first order. This transition is accompanied by the appearance of the intermediate state. The weak ferromagnetic phase exists up to T$\text{}_{c}$=240 K.
