Latest Patents

One of Yoshishige Suzuki's notable patents is the "Magnetic field feedback based spintronic oscillator." This invention relates to a microwave oscillator driven by DC current, utilizing a magnetic tunnel junction structure connected to a feedback waveguide. The oscillator operates by responding to fluctuations in the magnetization direction of the free magnetization layer of the magnetic tunnel junction (MTJ). These fluctuations drive an oscillating current through the feedback waveguide, which in turn exerts an oscillating magnetic field on the free layer, amplifying the magnetization fluctuations. If the DC current exceeds a critical value, continuous processing states of the magnetization become possible. Notably, the critical current is independent of the thickness and magnetization of the free layer. This innovation allows the MTJ to be driven into spontaneous oscillations, functioning as a spintronic microwave oscillator.
