Description
| - Exchange bias (EB) was investigated on heterostructures consisting of a stoichiometric UO2 film grown epitaxially on a LAO substrate and covered with highly textured Fe3O4 layers of variable thickness. EB reaching 2.6 kOe was observed at lowest temperatures in a bilayer with the thinnest Fe3O4. Magnetization measurements demonstrate that a remarkably large EB is present at temperatures higher than the bulk Neel temperature of UO2. The effects is complex: we suggest that it is provided both by strong exchange coupling between UO2 and Fe3O4 and by EB within magnetite. The former can be caused by proximity effects combined with a magnetic anisotropy of UO2, persisting above a continuous magnetic-ordering transformation. For magnetite, the results indicate the presence of pinned moments up to 120 K, that is a temperature of Verwey transition.
