The present invention relates to a spin torque oscillator with high power output and its applications. A spin torque oscillator may include a first magnetic reference layer having a fixed magnetization, a magnetic precession layer having a magnetization capable of precessing about an initial direction, and a first barrier layer interposed between the first magnetic reference layer and the magnetic precession layer. The first barrier layer is formed of an insulating material capable of inducing a negative differential resistance for the spin torque oscillator.

A magnetic multilayer film for a temperature sensor is disclosed. The magnetic multilayer film comprises: a bottom magnetic composite layer provided on a substrate, the bottom magnetic composite layer having a direct pinning structure, an indirect pinning structure, a synthetic ferromagnetic structure, or a synthetic anti-ferromagnetic structure; a spacer layer provided on the bottom magnetic composite layer; and a top magnetic composite layer provided on the spacer layer, the top magnetic composite layer having the direct pinning structure, the indirect pinning structure, the synthetic ferromagnetic structure, or the synthetic anti-ferromagnetic structure, wherein a ferromagnetic layer of the bottom magnetic composite layer closest to the spacer layer has a magnetic moment anti-parallel with that of a ferromagnetic layer of the top magnetic composite layer closest to the spacer layer.
