MAGNETIC DEVICE

To provide a magnetic device capable of achieving stable operation.SOLUTION: A magnetic device according to an embodiment includes a first conductive member and a first laminate. The first conductive member includes a first portion, a second portion, and a third portion between the first portion and the second portion. A direction from the first portion to the second portion is along a first direction. The first laminate includes a first magnetic layer, a first opposing magnetic layer, a first nonmagnetic layer, a first intermediate magnetic layer, and a first intermediate nonmagnetic layer. The first intermediate magnetic layer is between the third portion and the first opposing magnetic layer in a second direction that intersects the first direction. The first magnetic layer is between the first intermediate magnetic layer and the first opposing magnetic layer in the second direction. The first intermediate nonmagnetic layer is between the first intermediate magnetic layer and the first magnetic layer. The first nonmagnetic layer is between the first magnetic layer and the first opposing magnetic layer. A total magnetization amount of the first intermediate magnetic layer is smaller than a total magnetization amount of the first magnetic layer.SELECTED DRAWING: Figure 1 【課題】安定した動作が可能な磁気装置を提供する。【解決手段】実施形態によれば、磁気装置は、第１導電部材及び第１積層体を含む。第１導電部材は、第１部分と、第２部分と、第１部分と前記第２部分との間の第３部分と、を含む。第１部分から第２部分への方向は、第１方向に沿う。第１積層体は、第１磁性層、第１対向磁性層、第１非磁性層、第１中間磁性層及び第１中間非磁性層を含む。第１中間磁性層は、第１方向と交差する第２方向において第３部分と第１対向磁性層との間にある。第１磁性層は、第２方向において、第１中間磁性層と第１対向磁性層との間にある。第１中間非磁性層は、第１中間磁性層と第１磁性層との間にある。第１非磁性層は、前記第１磁性層と第１対向磁性層との間にある。前記第１中間磁性層の総磁化量は、第１磁性層の総磁化量よりも小さい。【選択図】図１
