FIELD: spintronics.
SUBSTANCE: invention relates to the field of spintronics, namely to broadband AC rectifiers made on the basis of a spin diode in the form of a heterostructure with a tunnel magnetic junction. The effect is achieved due to the fact that the specified heterostructure contains a first ferromagnetic layer, a tunnel non-magnetic layer and a second ferromagnetic layer in series. The average magnetization of the first and second layers is located in their plane. The heterostructure is made in such a way that the magnetization of at least one ferromagnetic layer is non-uniform. In this case, the vectors of local magnetization of the first mrl and second mfl layers, at least in part of the heterostructure, are noncollinear, and the rectification is realized in a nonresonant mode.
EFFECT: expanding the frequency band of AC rectification.
