Magetoresistance and Hall effect in oriented single crystal samples of n-type indium antimonide.

Measurements have been made on the angular dependence of the magnetoresistance effect and the Hall effect on oriented w-type indium antimonide samples. The measurements were taken at room temperature and liquid air temperature using a magnetic field strength of about 5000 gauss. Besides evidence of inhomogeneity, the results show directional dependence of the longitudinal magnetoresistance. The largest value was found in the (100) direction. This can be explained if, in addition to electrons at the central minimum, there is some filling of the {111} minima in k space
