  • Abstract
    This paper reports the process parameters for growing Al2 O3-doped Sr-ferrite magnetic thin films with an easy-axis in-plane orientation for the purpose of high density magnetic recording. It was found that for films thicker than 1200 Å, the magnetic properties of these Sr-ferrite thin films, viz. Hc=3.6 kOe, S=0.61 and SFD=0.38, could be easily achieved with conventional sputtering by controlling film thickness, annealing temperature, excess SrO and the amount of Al2O3 doping in the target
