Cobalt ferrite (CFO) thin films are good candidates for high density magnetic recording, spin filtering, and spintronic device applications. Previous reports showed that the cobalt ferrite (CFO) (111) thin films grown by different methods present complexities with regard to thin film quality and magnetic properties. This suggests that the magnetic properties of the CFO (111) film are dependent on film thickness and deposition parameters. In this study, we report the magnetic properties of CFO (111) thin films of different thickness grown on α-Al₂O₃ (0001). The purpose of this research is to understand thickness dependence behavior of the CFO (111) thin films.
