RF Signal Detection and Energy Harvesting with a Spin-Torque Diode Having Perpendicular Magnetic Anisotropy of the Free Layer
Abstract
We demonstrate theoretically that the out-of-plane regime of operation of a spin-torque diode (SD) can be achieved for the frequencies. 250 MHz without any external bias DC magnetic field, if the SDs free layer has a perpendicular magnetic anisotropy of the first and second order. We also show that such a device can operate as a broadband energy harvester capable of converting of an incident RF power to a DC power with conversion efficiency 5%. The developed analytical theory can be used for the development and optimization of high-efficiency RF detectors and energy harvesters based on spintronic diodes.
