Abstract Through applying GHz (Gigahertz) pulse current on the amorphous micro wire, we observed an increase in the coil voltage around the wire, and a sine function relationship between the coil voltage and the surrounding magnetic field. We assumed that the new performance of the coil voltage must be caused by the rotation of electron spins on the wire surface with GHz angular velocity, induced by the magnetic field force in the same direction, and proposed to name the observed new phenomena as GSR (Gigahertz Spin Rotation) effect. The developed GSR sensor presents excellent features with enhanced sensitivity and low hysteresis better than that of the GMI (Giant Magnetoimpedance) sensor. We developed the production technology to produce micro coils and developed a Micro-coil-on-ASIC (Application Specified Integrated Circuit) type GSR sensor, where the micro coils are directly formed on the ASIC surface, making small size GSR sensor possible.

GHz脉冲电流驱动的ASIC型微线圈GSR传感器的研制

摘要 通过在非晶微丝上施加GHz（千兆赫）脉冲电流，我们观察到导线周围的线圈电压增加，线圈电压与周围磁场之间呈正弦函数关系。我们假设线圈电压的新表现一定是由同一方向的磁场力感应出的电子自旋在导线表面以GHz角速度旋转引起的，并建议将观察到的新现象命名为GSR（千兆赫自旋旋转）效果。开发的 GSR 传感器具有比 GMI（巨磁阻抗）传感器更好的灵敏度和低磁滞的优异特性。我们开发了生产微型线圈的生产技术，并开发了 Micro-coil-on-ASIC（专用集成电路）型 GSR 传感器，
