Magnetism with picosecond field pulses
Abstract
Ultrashort magnetic field pulses of 6 ps duration surrounding the focus of 50 GeV electron bunches are shown to write a magnetic pattern into both perpendicular and in-plane metallic magnetic recording films. High-resolution magnetic contrast images reveal the elementary processes necessary to induce magnetization reversal as well as rotation of the magnetization into the field direction. © 1995.
