Abstract :
The magnetization within micrometer-size spots on Mn-Bi films was Curie-point switched with a laser in static applied magnetic fields. Such switching was found to be a continuous rather than a binary process, in that the average magnetization within a spot could be switched to any value between 
and 
by varying the applied field. The dependence of the magnetization after switching on field was measured quantitatively via the magnetooptic effect. Switched spots were examined under oil-immersion optics to reveal the magnetization distribution responsible for this dependence.
