Static and dynamic properties for switching the output nano-magnet.
The critical current density Jc0 is calculated as 4.68 MA/cm2 based on Eq. (1) and all the used parameters are listed in the Table 1. (a) Calculated effective perpendicular magnetic anisotropy energy density Keff and effective damping constant αeff as a function of nano-magnet width W. (b) Thermal stability Δ with respect to nano-magnet width W. (c) Calculation of the critical current Ic0 and current for 2 ns switching time Itsw=2ns as a function of square nano-magnet area AC. (d) The dependence of spin-torque switching efficiency Δ/Ic0 on nano-magnet width W.
