Circularly Polarized Electroluminescence of Spin LEDs with a Ferromagnetic (In, Fe)Sb Injector

The possibility of using a diluted magnetic semiconductor (In, Fe)Sb as a functional layer for use in spintronics, namely, as a ferromagnetic injector in a spin light emitting diode, has been investigated. The luminescent characteristics, as well as the temperature dependence of the circular polarization degree of of a spin LED electroluminescence with an (In, Fe)Sb injector, are studied.
