摘要：
Abstract: Spin-transfer ferromagnetic resonance in a planar external magnetic field is used to perform an experimental study of the effect produced by broadband rectification of a microwave current in magnetic tunnel junctions with perpendicular magnetic anisotropy. It is found that the parameters of broadband rectification (frequency range, rectified voltage, and the region of the mode of ferromagnetic resonance) depend on the size and its shape of the sample. The maximum rectified voltage is observed 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 sizes of 75 × 250 nm2. © Pleiades Publishing, Ltd. 2024.
