Current-driven asymmetric magnetization switching in perpendicularly magnetized CoFeB/MgO heterostructures


Reference: J. Torrejon et al., Phys. Rev. B 91, 214434 (2015).

By using analytical theory and micromagnetics simulations, we helped to explain experimental observations of an asymmetry in current-induced magnetization switching in ultrathin CoFeB/MgO films. This work has just appeared in Physical Review B.
