Magnetoresistance of Heavily Doped n- and p-Type Germanium at 4.2°K

Abstract

The anomalous magnetoresistance and planar Hall effect of heavily doped n - and p -type germanium have been measured at 4.2°K. The magnetoresistance consists of two components, i.e. , the ordinary and extraordinary components. It turned out that these components satisfy Seitz's formula under the weak field condition, and the upper limit of weak field range is entirely different between them. Some of the character of these components are presented.
