Abstract
We have imaged the magnetization reversal process of thin-film permalloy (Ni80Fe20) nanostructures using ballistic electron magnetic microscopy. Their switching behavior is often influenced by the formation of end domains and the subsequent domain-wall propagation under application of a magnetic field. Occasionally, this process leads to the formation of a 360° domain wall that is stable in fields which would otherwise switch the structure. The resulting state of the nanostructure in zero-applied field is very different from the near-single-domain state typically observed. The magnetization of the structure can show abrupt changes in a fixed magnetic field.This publication has 13 references indexed in Scilit:
