Abstract
A magnetic domain wall displacement type magnetic recording element which comprises: a first magnetization fixed part which is stacked in a first direction, a magnetic recording layer which includes a magnetic domain wall and extends in a second direction which crosses with the first direction, a non-magnetic layer which is provided between the first magnetization fixed part and the magnetic recording layer, and a first via part which is electrically connected to the magnetic recording layer, wherein at least a part of the first via part is located at a position which is apart from the first magnetization fixed part in the second direction in planar view observed from the first direction, the magnetic recording layer includes a first part which has a position where the first magnetization fixed part overlaps with the magnetic recording layer in planar view observed from the first direction, and a width of the first via part in a third direction which is orthogonal to the second direction is larger than a width of said position of the first part of the magnetic recording layer.
