Abstract: | The magnetization reversal of Fe/Cu(100) ultrathin films grown at
room temperature is investigated by using an in situ
magneto-optical Kerr effect polarimeter with a magnet that can
rotate in a plane of incidence. There occur spin reorientation
transitions from out-of-plane to in-plane magnetizations in 8 and 12
monolayers (ML) thick iron films. The coercive fields are observed
to be proportional to the reciprocal of the cosine with respect to
the easy axis, suggesting that the domain-wall displacement plays a
main role in the magnetization reversal process. |
