摘要：
Abstract: The operation of a spin-injection THz emitter is used to establish the possibility of competition between thermal and spin-injection (dynamic) radiation. It is shown experimentally that raising the intensity of dynamic radiation lowers that of thermal radiation. This is explained by the relationship between dynamic radiation and indirect interband spin-flip transitions accompanied by a change in momentum, and thus the absorption of phonons. © 2022, Allerton Press, Inc.
