Abstract: The spin-torque magnetic diode (STMD) effect [1] is a quadratic rectification effect of the input microwave current IRF(t) in a magneto-resistive nano-junction, which is commonly observed in a traditional regime of operation of an STMD, when the magnetization of the “free” layer lies in-plane, and when the frequency fs of the current IRF(t) is close to the ferromagnetic resonance (FMR) frequency f0 of the junction. It was demonstrated theoretically in [2] that in an STMD, biased by an out-of-plane static magnetic field, a novel dynamical regime of STMD operation characterized by large-angle out-of-plane magnetization precession can be realized.
