Notes:
Co-Zn ferrite films with small grains for magnetic recording media at ultrahigh density were deposited "plasma free'' on a substrate by using the dc facing targets sputtering apparatus without subsequent annealing process. The films deposited at a substrate temperature Ts as low as 90 °C were composed of crystallites with excellent (111) orientation and exhibited a saturation magnetization 4πMs of 3.3 kG and an in-plane and perpendicular coercivity Hc(parallel) and Hc⊥ of 1.8 and 2.2 kOe, respectively. The films deposited at a Ts of 250 °C exhibited 4πMs of 4.8 kG and possessed almost the same Hc(parallel) and Hc⊥ of 1.5 kOe.
