Аннотация: We demonstrate that a magnetic tunnel structure irradiated by microwaves can generate a typical voltage signal due to the rectification effect. We performed measurements in current-in-plane geometry when a current flows parallel to the interfaces in the structure. The value of the microwave-induced voltage strongly depends on the bПоказать полностьюias current and can be driven by a magnetic field. The rectification effect is discussed both in classical terms of nonlinearity of the current-voltage characteristics and within the mechanism involving the interplay between the spin-polarized current and the magnetization dynamics in the magnetic tunnel structure.
