Аннотация: We demonstrate that a magnetic tunnel structure irradiated by microwaves can generate a significant voltage signal due to the rectification effect. The measurements were carried out using current-in-plane geometry with a current flowing parallel to the interfaces in the structure. A value of the microwave-induced voltage strongly depends on a bias current and can be driven by a magnetic field. The rectification effect is discussed both in "Classical" terms of nonlinearity of the current-voltage characteristic and using a mechanism that involves the interplay between the spinpolarized current and magnetization dynamics in the magnetic tunnel structure.
