Indirect exchange coupling driven magnetization switching of CoNi/Cu/CoPt pseudo spin-valves with perpendicular magnetic anisot-ropy

摘要

Magnetic nanostructures with perpendicular magnetic anisotropy (PMA), as compared with the spin valves with in-plane anisotropy, have a lower level of thermal magnetization noise due to the high value of PMA, as well as a lower critical current density required for magnetization reversal nanostructures [1, 2].
