Ss. Bellad et al., PREPARATION AND CHARACTERIZATION OF SPRAY DEPOSITED CO-FERRITE THIN-FILMS, Indian Journal of Pure & Applied Physics, 35(9), 1997, pp. 565-567
Crystalline Co-ferrite (COFe2O4) thin films have been prepared by spra
y pyrolysis technique at an optimized substrate temperature of 325 deg
rees C. The thickness of the film is found to be of the other of 3 mu
m. The XRD study reveals the strong (111) orientation of the crystalli
tes in the film. The calculated cubic lattice constant is slightly gre
ater than the bulk value, indicating that the films are under strain.
The films show semiconducting behaviour with n-type conductivity.
