Abstract

　スピンバルブ素子に印加する外部磁場を弱くして、あるいは全く用いずに駆動してマイクロ波を発振させるために、一対の強磁性層の各層の保磁力が互いに異なっているスピンバルブ素子から電磁信号を得るスピンバルブ素子の駆動方法またはそのようなスピンバルブ素子。一対の強磁性層のうち保磁力の大きい強磁性層である固定層を、固定層の膜面にほぼ垂直になるような向きに磁化し、一対の強磁性層の一方から他方へ中間層を通過させて電流を流す。駆動の際、外部磁場の大きさの値とスピンバルブ素子に流す電流の値とからなる値の組を所定の条件を満たすようにする。あるいは、一対の強磁性層のうち保持力の小さい強磁性層であるフリー層の物性をこのような条件を実現し得るようなものとする。
