Magnetic tunnel junctions (MTJs) composed of ferromagnetic layers with perpendicular magnetic anisotropy (PMA) are of great interest for achieving high-density non-volatile memory and logic chips owing to its scalability potential together with high thermal stability. Recent progress has demonstrated a capacity for high speed performance and low power consumption through current-induced magnetization switching. In this manual, we present the utilization of a compact model of CoFeB/MgO PMA MTJ, a system exhibiting the best tunnel magneto-resistance ratio and switching performance. The MTJ structure consists of, from the substrate side, Ta(5)/Ru(10)/Ta(5)/Co20Fe60B20(1.3)/MgO(0.85)/Co20Fe60B20(1.3)/Ta(5)/Ru(5) (numbers are nominal thicknesses in nanometers). It integrates the physical models of static, dynamic and stochastic behaviors; many experimental parameters are directly included to improve the agreement of simulation with measurements.
