Abstract
An oscillator includes: a plurality of free layers and a non-magnetic layer disposed between the plurality of free layers. Each of the plurality of free layers has perpendicular magnetic anisotropy or in-plane magnetic anisotropy. Magnetization directions of the free layers are periodically switched such that a signal within a given frequency band oscillates.
