Anomalous exchange bias behavior in ion-beam bombarded NiCo/(Ni,Co)O bilayers

摘要

The structural and magnetic properties of NiCo/(Ni,Co)O bilayers were investigated. X-ray diffractometry results have shown that the top NiCo layer consisted of a fcc NiCo phase. The bilayer bottom was either a pure (Ni,Co)O or a composite [NiCo+(Ni,Co)O]
