Abstract

According to one embodiment, a magnetic memory apparatus includes a first stacked body and a controller. The first stacked body includes a first magnetic layer, a first counter magnetic layer, and a first intermediate layer placed between the first magnetic layer and the first counter magnetic layer. The first intermediate layer is nonmagnetic. The controller is electrically connected to the first magnetic layer and the first counter magnetic layer. The controller is configured to perform a first operation of supplying first pulse current to the first stacked body. The first pulse current includes a first constant-current period. A first electrical resistance value of the first stacked body before the supply of the first pulse current is different from a second electrical resistance value of the first stacked body after the supply of the first pulse current.
