项目摘要
Temperature dependence of the critical current density of spin transfer torque switching for the CPP-GMR device with rare earth - transition metal alloys has been investigated to show the possibility of the energy efficient writing by controlling the energy barrier of the magnetization switching, and the reduction of the critical current density with temperature was confirmed. Moreover, the ultra-thin Co films were micro-fabricated by the lithography technique and their hysteresis loops with and without an electric field were measured by the anomalous Hall effect to study the effect of the electric field on the energy barrier of the magnetization switching of the ultra thin Co layer.
研究了稀土-过渡金属系CPP-GMR器件自旋转移扭矩转换的临界电流密度与温度的关系,证明了通过控制磁化转换的能垒来实现能量有效写入的可能性,并证实了临界电流密度随温度的降低。此外,利用光刻技术制备了Co超薄薄膜,并利用反常霍尔效应测量了其在电场作用下的磁滞回线,研究了电场对Co超薄薄膜磁化转变势垒的影响。
