Perpendicular exchange bias was investigated using Pt/Co/α-Cr2O3(0001) thin films prepared by a reactive DC magnetron sputtering method. On the α-Cr2O3(0001) layer, the Pt/Co thin film simultaneously showed perpendicular magnetic anisotropy (PMA) and perpendicular exchange bias (PEB). Although PEB was not observed at room temperature, it suddenly appeared, accompanied by a unique temperature dependence. The suddenly appearing PEB was as large as a unidirectional magnetic anisotropy energy, JK, of about 0.29 erg/cm2. The mechanism of the sudden appearance of JK is discussed on the basis of Meiklejohn and Bean's exchange anisotropy model.
