Microwave-induced spin-flip scattering of electrons in point contacts

Microwave-induced spin-flip scattering of electrons in point contacts

We investigate resonant interaction of conduction electrons with an electromagnetic field that irradiates a point contact between a ferromagnetic and a normal metal in the presence of a strong magnetic field of order 1 T. We show that electron spin-flips caused by resonant absorption and stimulated...
