The spin switch oscillator: A new approach based on gain and feedback

Abstract

We propose a new kind of oscillator based on incorporating feedback into a transistor-like amplifying device namely the spin switch. Unlike the present-day state-of-the-art spin transfer nano oscillators (STNO) based on the delicate balancing of magnetic fields and spin currents, this spin switch oscillator (SSO) should exhibit high tunable output power without the need of external magnetic fields.
