Spin-injection radiation of terahertz waves in ferromagnetic structures. (Russian, English) Zbl 1299.82021

Dokl. Akad. Nauk, Ross. Akad. Nauk 451, No. 4, 397-398 (2013); translation in Dokl. Phys. 58, No. 8, 347-348 (2013).
Summary: We propose and discuss the mechanisms of terahertz sd exchange radiation during transmission of the spin-polarized current in a structure from a thin steel rod pressured to an ultrathin ferromagnetic film. The two mechanisms considered are quantum transitions between the quasi-Fermi levels in the film near the rod and the precession of injected spins around the film magnetization.
