[en] Experimental data on anisotropy of thermo-emf and electric resistance in beryllium in the temperature range of 120-1480 K are given. Weak anisotropy of electric resistance in 400-1000 K and its complete disappearance at higher temperatures were established. For the first time the coexistence of high anisotropy of thermo-emf and absence of electric resistance anisotropy were observd which, obviously, can be related to peculiarities of highly anisotropic Fermi surface of beryllium

[en] Results are presented of experimental investigation of praseodymium and neodymium thermo-emf and electric resistance in the 800 to 1450 K temperature range. It has been found that at temperatures of polymorphous transformation and melting points the electric resistance jumps for both metals are approximately the same, while during melting the thermo-emf changes much less than during polymorphous transformation. This testifies to the similarity of electronic structure of these metals both in solid and liquid phases rear the melting point

[en] We present experimental results on magnetotransport in (Y_xGd_1-x)Co₂ alloys, where the localized Gd-moments are coupled antiferromagnetically to the itinerant Co 3d electrons. The alloys are paramagnetic for x>0.85. The transport properties of the paramagnetic alloys show Kondo like anomalies. On approaching to the magnetic phase boundary from the paramagnetic region the resistivity reveals non-Fermi liquid (NFL) behaviour, indicating a presence of apparently gap-less magnetic excitations

[en] We present experimental results on thermopower of (Y_1-xGd_x)Co₂ alloys at temperatures from 2 to 500 K in magnetic fields up to 15 T. The variation of thermopower with the alloy composition is explained as arising from a combination of structural disorder and itinerant metamagnetism of 3d electron system

[en] Measurements of Hall constant R, thermoelectromotive force coefficient S and electrical resistance ρ were carried out, using the same sample YBa₂Cu₃O_7-δ high-temperature superconducting (HTSC) ceramics at 100-450 K temperatures. It is shown that valid selection of conductivity model in new HTSC materials normal state requires comprehensive study and analysis of kinetic events complex within wide range of temperatures and current carrier densities and, apparently, with regard to fermi-liquid effects

[en] An attempt was made to construct theory of high-temperature thermo-emf of rhenium, which behaviour was characterized by sufficient anomalies. Peculiarities of analyzed carrier spectrum enable to explain thermo-emf anisotropy. Theoretically constructed temperature dependence of thermo-emf in 300-1000 K range corresponds satisfactorily with the curve, obtained in experiments

[en] The thermoelectric power (TEP) S was measured for all the rare earth metals except promethium, in the temperature range 80-1000 K. Data are also presented for scandium and yttrium. The available published data on the thermopower of the rare earths above 4.2 K are also presented. The TEP temperature dependence of almost all the rare earths were found to be similar. Measurements of the electrical resistivity rho of almost all the metals were made in the same temperature range. The Hall constants R of gadolinium, terbium and dysprosium were also measured. (Auth.)
