| 内容記述 | 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 α-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. | |||||
