Abstract (in Japanese) (See Japanese page) 
(in English) We investigated perpendicular exchange bias of Pt/Co/α-Cr2O3(0001) thin films which were fabricated by means of DC magnetron sputtering method. The Pt/Co bilayer which was deposited on α-Cr2O3(0001) layer has perpendicular magnetic anisotropy (PMA) and perpendicular exchange bias (PEB). Although PEB is not observed at RT, it appears suddenly at a given temperature, and it had a unique temperature dependence. Unidirectional magnetic anisotropy energy, JK of about 0.29 erg / cm2 is obtained. The mechanism of suddenly appearance of JK is discussed on the basis of Meiklejohn and Bean’s exchange anisotropy model.
