Abstract

Current-induced magnetization reversal of perpendicularly magnetized layers was studied in current-perpendicular-to-plane giant magnetoresistance pillars with L 10 -FePt (001) layers. The FePt layers exhibited strong perpendicular magnetic anisotropy of the order of 107 erg cm3. A series of magnetoresistance curves after applying pulse currents with different current densities showed that current-induced magnetization reversal from an antiparallel to a parallel alignment occurred at the current density of the order of 108 A cm2 with the assistance of magnetic field.
