Abstract:
According to one embodiment, a magneto-resistive effect device includes a stacked body, a pair of electrodes for supplying current in a stacking direction of the stacked body. The stacked body includes a first magnetic layer, a second magnetic layer, and a spacer layer disposed between the first magnetic layer and the second magnetic layer. At least one of the first magnetic layer, the second magnetic layer, and the spacer layer includes an oxide layer formed from a metal oxide. A crystalline structure of the metal oxide is a NaCl structure.
