【摘要】 电流感应的磁化翻转效应是近年来继巨磁阻效应(GMR)和隧道磁阻效应(TMR)之后提出的一种nm尺度下新的自旋相关效应,在无外加磁场的情况下,垂直于铁磁层平面的自旋极化电流就能引起铁磁层的磁化翻转。该效应有望被用于制作新型的电流操纵磁存储器件。报道了该效应的理论和实验的研究进展。更多还原

【Abstract】 A novel spin-dependent effect,current-induced magnetization switching(CIMS),was put forward in recent years after giant magnetoresistive(GMR)and tunneling magnetoresistive(TMR)effects. According to CIMS effect,the magnetization of ferromagnetic film can be switched by a spin-polarized current perpendicular to the film plane,without external magnetic field. Therefore,it is promising that a new type of magnetic random access memory operated only by current can be realized based on this effect. The progresses on its theories and experiments were introduced.更多还原
