FIELD: physics.
SUBSTANCE: present invention relates to wireless transmission of energy and information, as well as detection of an alternating signal and is a receiver or detector based on a vortex spin diode (which is a rectifying element), operating due to the spin transfer effect and the tunnel/giant magnetoresistance and representing a magnetic multilayer heterostructure. Technical result is achieved by using a spin diode effect in a magnetic multilayer heterostructure with a free ferromagnetic layer having a vortex distribution of magnetization.
EFFECT: technical effect of the present invention is to increase the sensitivity of the receiver, expand the range of power of the input signal, at which effective operation is possible, as well as shift of resonance frequencies of efficient operation to the range of hundreds of MHz - units of GHz.
