Galvanomagnetic effects in n-Ge in the impurity conduction range

Measurements of the magnetoresistance and magnetic field dependence of the Hall coefficient of several samples of n-type germanium in the impurity conduction range have been made employing magnetic field strengths up to 28 kgauss. The magnitude and the crystalline anisotropy of the magnetoresistance are interpreted in terms of the changes in the donor wave functions which are produced by the magnetic field. The field dependence of the Hall coefficient is interpreted as a magnetoresistance effect of the conduction band. © 1961 The American Physical Society.
