Effect of anisotropic intersheet electron scattering and Fermi surface anisotropy on the galvanomagnetic properties of rhenium

Galvanomagnetic properties of rhenium single crystals with residual resistance ratios up to 38 000 were investigated in the temperature range 4.2 to 273.2 K and in magnetic fields up to 22 kG. A sign inversion and nonmonotonic temperature dependence of the Hall coefficient Rsub(H)(T) have been observed. It is suggested that the observed sign inversion and the minimum in Rsub(H)(T) dependence for H parallel <0001> are due to the phonon-induced electron transition between the hole sheets L7h and due to a change over from the low to high magnetic field regime. The temperature dependence of the conductivity in magnetic field for H parallel <0001>5σsub(Hi)(T) approximately T4 is observed at T<20 K
