Resumo
We experimentally studied the effect of broadband rectification of microwave current in magnetic tunnel junctions with perpendicular magnetic anisotropy with using the method of spin-transfer ferromagnetic resonance in a planar external magnetic field. It was found that the parameters of broadband rectification (frequency range, rectified voltage value and the region of existence of the ferromagnetic resonance mode) depend on the size of the sample and its shape. The maximum value of the rectified voltage was on a round elliptical sample of 100×150 nm. At the same time, the widest operating frequency range of approximately 2 GHz was observed on strongly elliptical MTJs with the size of 75×250 nm.
