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.
已开发出一种用于测定霍尔迁移率的无电极（双感应）技术。对七个固态或液态金属样品进行了测量，并将结果与报道的迁移率进行了比较。在1 A的电流和100 G的磁场下，对铜、银或金样品测得的信号为100 nV，同时可测得低至50 pV的信号。已确定了低至2×10⁻⁶弧度的霍尔角。强调了该技术在对出现与电极有关结果的系统或电极不稳定的腐蚀性材料进行霍尔迁移率测量中的实用性。
