Longitudinal Photomagnetoelectric Effect in Germanium

Abstract

The emf developed parallel to the gradient of light absorption (Dember emf) in a germanium crystal is reduced by the application of a transverse magnetic field, the diminution being about 10% for a field of 5000 gauss. The size of the effect is approximately quadratic in the field up to about 2000 gauss, is then linear to 4000 gauss, and subsequently saturates.
