Both effective anisotropy (Keff) and PMA constant (KU) reached a maximum at n=8. When the 3 nm Pt underlayer was deposited at low energy condition, the Keff and KU of (CoFe/Pt)8 are 4.0 and 6.1 Merg/cc, respectively. On the other hand, the Keff and KU increased to 6.8 and 9.7 Merg/cc, respectively, when the Pt underlayer deposited at high energy condition. As the n increases, the surface roughness monotonously increases and d111 inside the superlattice layers increase and relax from bottom to top part. The interface roughness and relaxation in superlattice reduce the PMA considerably. @ 2016 Author(s). | Source Title: | AIP Advances | URI: | https://scholarbank.nus.edu.sg/handle/10635/183338 | ISSN: | 21583226 | DOI: | 10.1063/1.4944520 | Rights: | Attribution 4.0 International |
