摘要

从微波探测器到能量采集器，自旋力矩二极管在许多应用领域都显示出巨大的潜力和性能。在这项工作中，我们使用微磁模拟来研究室温下最先进的非谐振低频尾自旋转矩二极管的直流输出电压作为沿不同方向施加的面内外场振幅的函数。我们发现，注入的交流电流存在一个阈值，该阈值促进了磁场输出电压的线性行为，直至pT范围，并且我们建议利用这种行为来设计磁场传感器。

Magnetic field sensor based on a low-frequency-tail spintronic diode

Spin-torque diode have shown great potentials and performance in many applicative fields, from microwave detectors to energy harvesters. In this work, we use micromagnetic simulations to study, at room temperature, a state-of-the-art non-resonant low-frequency-tail spin-torque diode in terms of dc output voltage as a function of the amplitude of an in-plane external field applied along different directions. We find that there exists a threshold value of the injected ac current that promotes a linear behavior of the output voltage of field down to the pT range, and we suggest exploiting such a behavior for the design of a magnetic field sensor.
