Double induction method for electrodeless determination of Hall mobility.
An electrodeless (double induction) technique has been developed for the determination of Hall mobility. Measurements were performed on seven solid or liquid metallic samples and the results compared to reported mobilities. With a current of 1 A and magnetic field of 100 G, signals of 100 nV were measured for Cu, Ag, or Au samples, while signals as low as 50 pV can be measured. Hall angles as small as 2 x 10(-6) rad have been determined. The usefulness of this technique in Hall mobility measurements on systems in which electrode dependent results occur or in corrosive materials on which no electrode is stable is emphasized.
