Co/Co 3 O 4 bilayers were fabricated by magnetron sputtering with Co and Co 3 O 4 targets. The exchange bias effect was observed at 80K, which was much higher than the N• el temperature of Co 3 O 4 (about 40K). X-ray photoelectron spectroscopy results showed that CoO was formed near the Co/Co 3 O 4 interface, probably due to diffusion of oxygen atoms. The angular dependence of exchange coupling in Co/Co 3 O 4 bilayers could not be satisfied with simple cosine function, and the position of the maximum of exchange bias departed from the FM easy axis. The mechanism including rotatable anisotropy and movement of domain wall in AF was used to explain the experiment results.

Graphite Intercalation

Electron microscopy can be used to study structures and phase transitions occurring in graphite intercalations compounds. The fundamental symmetry in graphite intercalation compounds is the staging periodicity whereby each intercalate layer is separated by n graphite layers, n denoting the stage index. The currently accepted model for intercalation proposed by Herold and Daumas assumes that the sample contains equal amounts of intercalant between any two graphite layers and staged regions are confined to domains. Specifically, in a stage 2 compound, the Herold-Daumas domain wall model predicts a pleated lattice plane structure.
