<P>PROBLEM TO BE SOLVED: To provide a ferromagnetic tunnel junction element capable of current-induced magnetization reversal with a low drive current value. <P>SOLUTION: In a ferromagnetic tunnel junction element 10 having a magnetization fixed layer 100, a nonmagnetic insulating layer 110 and a magnetization free layer 120, the magnetization free layer 120 has ferromagnetic layers 220, 222 sandwiching a nonmagnetic metal layer 221, and the magnetization directions of the two ferromagnetic layers 220, 222 are in parallel with each other. Since the magnetization directions of the two ferromagnetic layers are in parallel with each other, spin transfer torque works effectively and the drive current can be reduced. <P>COPYRIGHT: (C)2013,JPO&INPIT |
