DC to AC conversion using magnetoresistance

The magnetoresistance effect when used as a rectifier offers the possibility of low off field resistance with high current capabilities. This type of controlled rectifier in action is essentially independent of applied voltage. Possible applications exist where low voltage high current switching is needed. Various device configurations of InSb and Bi were studied experimentally and to a limited extent theoretically at room temperature and at liquid nitrogen temperature. An off field to on field resistance ratio of 52 to 1 was obtained at room temperature and 175 to 1 at liquid nitrogen temperature. An analog computer study was made to compute theoretical efficiencies of DC to AC conversion for various magnetic fields and various off field to on field resistance ratios.
