Abstract: This discovery of a system of materials exhibiting ferrimagnetic and semiconducting properties at room temperature, makes possible the development of classes of devices not previously realizable in the absence of refrigeration. These materials in polycrystalline and single-crystal form find application in such devices as optically modulated magnetic devices, microwave amplifiers with built-in isolation and memory elements with built-in gain.
