【 摘 要 】

Spin light-emitting diodes based on GaAs/InGaAs/AlGaAs heterostructures with a ferromagnetic CoPt injector have been fabricated and studied. To obtain stability of diodes at higher temperatures, heterostructures with three different combinations of a quantum well and barriers have been studied. A stable 2% circular polarization degree of electroluminescence was obtained at temperatures up to 300 K.
