Abstract

CdFe2O4 thin films have been prepared by a sputtering method, and their structural and magnetic properties have been examined. As-deposited film shows magnetic transition like that of cluster-spin glass or superspin glass, and possesses large magnetization even at room temperature. The magnetic behaviors are partly attributed to crystal structure with a random distribution of cations in CdFe2 O4 nanocrystals. Annealing of the as-deposited film at 200 °C leads to an increase in magnetization while the magnetization is decreased when the film is annealed at 400 °C. The effect of annealing on the magnetic properties has been discussed in terms of the change of microstructure as well as chemical structure of the thin films.
