Abstract

The effects of angular momentum compensation on domain wall motion are considered. Particular attention is paid to the dynamic parameters of the wall in response to effects brought about by the approach to the angular momentum compensation temperature. When the wall gets close to the angular momentum compensation point, the net angular momentum is effectively lowered, thus causing the mobility of the wall to increase markedly. This unusual behavior is believed to be responsible for the erase process in single-layer direct-overwrite magnetooptical recording media.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
