Abstract:
1. A high-frequency magnetic field generation element comprising: a first fixed layer, a direction of a magnetization of the first fixed layer being fixed and including a component parallel to a first direction; a first free layer stacked with the first fixed layer, a direction of a magnetization of the first free layer being variable and including a component orthogonal to the first direction; and a second free layer stacked with the first fixed layer, a direction of a magnetization of the second free layer being variable and including a component orthogonal to the first direction, the first fixed layer being provided between the first free layer and the second free layer, the first direction being parallel to a stacking direction of the first fixed layer, the first free layer, and the second free layer, the magnetization of the first free layer and the magnetization of the second free layer oscillating by a current flowing through the first free layer, the second free layer, and the first fixed layer, and a rotation direction of the magnetization in the oscillation of the first free layer being opposite to a rotation direction of the magnetization in the oscillation of the second free layer.
