Highly crystal textured copper ferrite films have been grown on (100) MgO substrates using pulsed laser deposition. Deposition temperatures were varied from 600–900 °C, with deposition oxygen pressure varied from 1 mTorr to 120 mTorr. Saturation magnetization was measured to increase monotonically with substrate temperature approaching the bulk value of 1700 G near 900 °C. Magnetization was also shown to increase with oxygen pressure with a maximum value of 2481 G obtained at a pressure of 90 mTorr. Although divalent Cu prefers octahedral sites (i.e., 85% under equilibrium conditions), cation inversion was measured to decrease with increasing oxygen pressure and magnetization.
