Abstract
The paper describes experiments carried out at 4000 Mc/s on a crystal of n-type germanium mounted in a resonant cavity magnetically coupled to a waveguide of rectangular section supporting an H01 wave mode. By this means the crystal was immersed in a comparatively strong microwave magnetic field and at the same time arrangements were made to pass through the crystal a current at right angles with that magnetic field and proportional to the electric field of the waveguide.A Hall effect in the germanium was observed under these conditions, and the time average of the Hall e.m.f. was found, when suitable phasing adjustments were made, to bear an approximately linear relationship to the power in the waveguide, reversing its sign with reversal of direction of the power.Keywords
