Mn-Co-Cu SPINEL FERRITE FILMS -NEW PROSPECTIVE MATERIAL FOR MAGNETO-OPTICAL RECORDING APPLICATIONS

Cubic spinel ferrite films containing cobalt, copper and manganese were prepared by the rf sputtering from targets formed by intimate mixtures of ferrite powders. Additional heat-treatments at temperatures of about 450°C introduce cation vacancies which have positive influence on the magneto-optical...

Zusammenfassung:Cubic spinel ferrite films containing cobalt, copper and manganese were prepared by the rf sputtering from targets formed by intimate mixtures of ferrite powders. Additional heat-treatments at temperatures of about 450°C introduce cation vacancies which have positive influence on the magneto-optical properties of films. Figure of merit shows maxima at 600, 850 and 1500 nm which classifies these films to promissing materials for magneto-optical recording.
