| Popis: | Ultrathin [Co/Pt] n superlattice films consisting of 0.18–0.60-nm-thick Co and Pt sublayers were deposited by sputtering. A large in-plane saturation field (H s) of ∼39 kOe and a very large effective perpendicular magnetic anisotropy (K eff) with a magnitude of 107 erg/cm3 were attained. The highest K eff was ∼1.40 × 107 erg/cm3. These films are promising candidates for the reference layer of the p-MgO magnetic tunnel junction in Gb-scale magnetic random-access memory. |
