摘要:

自旋-轨道转矩(SOT)磁阻(MR)器件已经吸引了用于下一代MR器件的注意力。已知SOT装置基于自由层的磁化方向与写入电流方向之间的相对角度而展现不同写入特性。然而,很少有研究比较每种类型的写入特性的报告。在这项研究中,我们测量了外部垂直磁场依赖的阈值写电流密度和写电流开关概率使用两种类型的面内磁化SOT-MR器件。

英文摘要:

Spin-orbit torque (SOT) magnetoresistance (MR) devices have attracted attention for use in next-generation MR devices. The SOT devices are known to exhibit different write properties based on the relative angle between the magnetization direction of the free layer and the write-current direction. However, few studies that compare the write properties of each type have been reported. In this study, we measured the external perpendicular-magnetic field dependence of the threshold write current density and the write current switching probability using two types of in-plane magnetization SOT-MR devices.
