Abstract

In granular bismuth, electrical resistivity with T1/2 dependence was observed in the low temperature range 0.5-4.2 K, while anomalous positive magnetoresistance was found in this range. This anomalous magnetoresistance, which increases with decreasing temperature, is farily well explained by the three-dimensional localization theory taking account of the effect of strong spin-orbit interaction. The spin-orbit scattering time Tso is estimated as 4 x 10-13 sec, and the inelastic scattering time changes in proportion to On the other hand, dependence of resistivity seems due to the interaction effect between electrons.
