Abstract

The GigaHertz spin rotation (GSR) effect was observed through the excitement of Giga Hertz (GHz) pulse current flowing through amorphous wire. The GSR sensor that was developed provides excellent features that enhanced magnetic sensitivity and sine functional relationship, as well as good linearity, absence of hysteresis, and low noise. Considering the GHz frequency range used for the GSR sensor, we assume that the physical phenomena associated with the operation of the sensor are based on spin reduction and rotation of the magnetization. The proper production technology needed was developed and a micro-sized GSR sensor was produced by directly forming micro coils on the surface of the application-specific integrated circuit (ASIC). Some prototypes of the ASIC type GSR sensor have been produced in consideration of applications such as automotive use, mobile device use, and medical use. Therefore, we can conclude that GSR sensors have great potential to become promising magnetic sensors for many applications.

摘要

通过流经非晶丝的吉赫兹（GHz）脉冲电流的激发，观察到了吉赫兹自旋旋转（GSR）效应。所开发的GSR传感器具有出色的特性，如增强的磁灵敏度和正弦函数关系，以及良好的线性度、无磁滞和低噪声。考虑到GSR传感器使用的GHz频率范围，我们假设与传感器操作相关的物理现象基于磁化强度的自旋减少和旋转。开发了所需的适当生产技术，并通过在专用集成电路（ASIC）表面直接形成微线圈来制造微型GSR传感器。考虑到汽车应用、移动设备应用和医疗应用等，已经生产了一些ASIC型GSR传感器的原型。因此，我们可以得出结论，GSR传感器在许多应用中具有成为有前景的磁传感器的巨大潜力。
