Abstract
A magnetic domain wall displacement element includes a first ferromagnetic layer, a second ferromagnetic layer extending in a second direction and magnetically recordable, a nonmagnetic layer, and a first conductive part having a first intermediate layer and a second conductive part having a second intermediate layer, in which the first intermediate layer is sandwiched between first and second magnetization regions and exhibiting first and second magnetization directions, the second intermediate layer is sandwiched between a third magnetization region and exhibiting the second magnetization direction and a fourth magnetization region exhibiting the first magnetization direction in the first direction, and an area of the first magnetization region is larger than an area of the second magnetization region and an area of the third magnetization region is smaller than an area of the fourth magnetization region in a cross section in the first direction and the second direction.
