Abstract

The effect of spin-transfer torque in 90° magnetization configuration on current-induced magnetization reversal was studied in current-perpendicular- to-plane giant magnetoresistance pillars of in-plane magnetized FePtAuFePt trilayers combined with an L 10 -FePt perpendicular spin polarizer. The resistance change associated with the transition of the alignment of the two in-plane magnetizations was observed, showing no significant difference in the magnitude from that of a pillar without the perpendicular spin polarizer. However, the spin-transfer torque from the perpendicular spin polarizer reduced the current density for the magnetization reversal of the in-plane magnetization.
