The morphology of these films and correlation with their magnetic properties has been investigated. Films grown at temperatures below ~ 750oC have up to 90% of Cr occupying substitutional sites. Post-growth annealing at 825oC results in a systematic drop in the fraction of substitutional Cr as well as a fall off in the ferromagnetic signal.
