Abstract:
1. A magneto resistive effect element comprising: a pinned layer with a fixed magnetization direction; a recording layer with a variable magnetization direction; and a first non-magnetic layer disposed between the pinned layer and the recording layer, wherein: one of the pinned layer and the recording layer is formed from a ferromagnet including at least one type of a 3d transition metal and enabling the magnetization direction to be changed from a parallel direction to a perpendicular direction with respect to a film plane by a film thickness control; the magnetization direction is oriented in the perpendicular direction with respect to the film plane by the film thickness control; and a ferromagnetic layer that forms the pinned layer has a film thickness smaller than the film thickness of the recording layer.
