“…For comparison, data of ͑111͒-oriented film with 100% orientation, as obtained by sputtering at 50 W rf power and 15% oxygen, have been given in the table. 13 A high perpendicular coercivity has been observed for all slow-cooled samples having preferred orientation either in ͑400͒ or ͑311͒. The perpendicular coercivity of the about 3000 Oe and higher, and parallel coercivity about 1000 Oe and higher, remanence ratio M r Ќ / M s Ќ of about 0.6 in the direction perpendicular to the film plane, and low M r ʈ / M s ʈ in the film plane has been obtained.…”

Copper ferrite thin films, radio-frequency sputtered at 200 W, on fused quartz substrates, postannealed at about 800°C and slow cooled, exhibited a tetragonal copper ferrite phase, but with a preferred orientation of mainly a ͑311͒ or ͑400͒ peak. The films show a perpendicular coercivity of about 3000 Oe or more, almost two times the parallel coercivity. Magnetocrystalline anisotropy is the major cause of the high coercivity observed in these films. The perpendicular anisotropy of these films is attributed to the texture with the hard axis in the film plane as seen by texture measurement.

“…There have been reports of deposition of oriented thin films on quartz substrates and also by using buffer layers [3][4][5][6]. However, most of them grow in a fashion such that the plane of the closest packing is along the plane of the film.…”

“…These compounds are capable of giving nanoferrites by thermal decomposition [2]. Literature survey reveals that very few attempts have been made to prepare CuFe 2 O 4 in thin film form at low temperature, despite of its potential applications in magneto-optic recording and microwave devices [3][4][5]. Thin films of CuFe 2 O 4 could be especially interesting for information storage.…”
