Abstract:
1. A magnetic element comprising: a channel layer; a first magnetic electrode which is in contact with the channel layer; a second magnetic electrode which is in contact with the channel layer and is insulated from the first magnetic electrode; a first intermediate layer which is provided adjacent to the first magnetic electrode and has a first insulating layer; a first magnetic layer which is provided in contact with a surface of the first intermediate layer on an opposite side to a surface contacting the first magnetic electrode to transfer magnetization to the first magnetic electrode; a first electrode which is connected to the first magnetic electrode; a second electrode which is connected to the second magnetic electrode, at least one of the first electrode and the second electrode outputting a first signal which changes depending on a magnetic arrangement of the first magnetic electrode and the second magnetic electrode; a second magnetic layer; a second intermediate layer which is formed between the first magnetic layer and the second magnetic layer; a third electrode which is connected to the first magnetic layer; and a fourth electrode which is connected to the second magnetic layer, the third electrode and the fourth electrode supplying a second signal to control a magnetization direction of the first magnetic layer, and in which a magnetic coupling acts between the first magnetic electrode and the first magnetic layer through the first intermediate layer.
