Abstract
A barium ferrite layer with low-Ba content was used as an underlayer f or a high-Ba content barium ferrite thin film During the post-depositi on annealing, the underlayer which has a lower nucleation rate than th e top layer prevented grains from nucleating in the interdiffused regi on at the interface with the substrate. As a result, the magnetic prop erties were dramaticallyimproved as indicated by much higher coercivit y squareness S and narrower switching field distribution.
