Zinc-ferrite (ZnFe2O4 (ZF)) films were prepared by pulsed laser deposition. The film deposited without magnetic field at 500 °C showed low magnetization of 7.43 emu/g measured at room temperature. Application of magnetic field (2000 G) during deposition of ZnFe2O4 films increased the magnetization up to 56.6 emu/g. This suggests that random distribution of Zn2+ and Fe3+ cations was brought about by the external magnetic field during deposition. After annealing over 600 °C, the magnetization was drastically decreased.
