Abstract
A magnetic miniaturized memory element with improved thermal stability of magnetization includes a first magnetic layer, an insulating layer that is formed on the first magnetic layer, a second magnetic layer that is formed on the insulating layer, and an expanded interlayer insulating film that comes into contact with side surfaces of the first and second magnetic layers, where at least one of the first magnetic layer and the second magnetic layer is strained and deformed so as to be elongated in an easy magnetization axis direction of the first magnetic layer or the second magnetic layer or compressive strain remains in any direction in the plane of at least one of the first magnetic layer and the second magnetic layer.
