抄録	Perpendicular exchange anisotropy at the Co/α-Cr₂O₃ interface was investigated using the two types of films: the film with the single crystalline α-Cr₂O₃ and that with the twinned a-Cr₂O₃. Exchange anisotropy energy density JK of the film with the single crystalline α-Cr₂O₃ was ~0.09 erg/cm² whereas JK of the film with the twinned α-Cr₂O₃ was ~0.43 erg/cm², more than 4-times enhancement. We discussed the mechanism of the enhancement of JK based on the exchange coupling at the twin boundary and that the spin frustration at the twin boundary can be the origin of the enhancement of JK.
