Abstract :
We present a physical compact model for magnetic tunnel junction (MTJ). Landau-Lifshitz-Gilbert (LLG) differential equation is solved in SPICE to derive the transient characteristics of MTJ. A modified version of the Simmons tunnel current equation captures the steady state properties of MTJ. The model results are validated with published experimental data.
