摘要: According to one embodiment, a high-frequency magnetic field generation element includes a first fixed layer, a first free layer, and a second free layer. A direction of a magnetization of the first fixed layer is fixed and has a component parallel to a first direction. A direction of a magnetization of the first free layer is variable and has a component orthogonal to the first direction. A direction of a magnetization of the second free layer is variable and has a component orthogonal to the first direction. The first fixed layer is provided between the first free layer and the second free layer. The magnetizations of the first free layer and the second free layer oscillate. A rotation direction of the magnetization of the first free layer is opposite to a rotation direction of the magnetization of the second free layer.
