  • Ultrafast magnetization reversal
    Patent number: 6700720
    Abstract: A scheme for ultrafast magnetization reversal in an in-plane magnetized layer (3) is disclosed. For that, an external magnetic field {right arrow over (H)}ex is applied such that the magnetization {right arrow over (M)} precesses around the external magnetic field {right arrow over (H)}ex and the external magnetic field {right arrow over (H)}ex is maintained until the precession suffices to effect the magnetization reversal. The external magnetic field {right arrow over (H)}ex is applied approximately perpendicular to the magnetization {right arrow over (M)}.
