Spin torque oscillator and magnetization switching in double-barrier Rashba Zeeman magnetic tunnel junction

In this letter, we have studied the spin torque based magnetization oscillations and switching in presence of Rashba - Zeeman (RZ), Ruderman Kittel Kasuya Yoside (RKKY) Dzyaloshinskii Moriya (DM) interactions a double barrier RZ$|$Heavy Metal (HM)$|$RZ magnetic tunnel junction (MTJ). The system has stable can work as an oscillator or switcher for significant difference strength RKKY DM interaction under suitable transfer (STT). For proposed with same order interaction, nonlinear characteristic oscillation is observed. However, nonlinearity be reduced by external field considering material RZ interaction. addition to this, our study reveals tuned using STT. A dependence time on layer thickness also Also, speed increases systems having either dominated An opposite seen when dominates over
