Abstract
The electrical resistivities of single crystals of LaB6 and ReO3 were measured in the temperature ranges of 4.2-360K and 4.2-300K, respectively. The residual resistance ratio of LaB6 was 450 and that of ReO3 was 90. The resistivity value of LaB6 at 300K is 8.90*10-6 Omega cm and for ReO3, 10.5*10-6 Omega cm. The experimental data were analysed from the scattering of electrons by polar optical phonons in addition to the scattering by acoustic phonons and impurities. The temperature dependences of the resistivities were explained well by this model for the temperature range measured, taking the Debye and the Einstein temperatures as 245 and 920K for LaB6 and 330 and 800K for ReO3, respectively.Keywords
