  • Abstract
    An electrodeposition process was developed for making cobalt-iron thin film. It was found that the electroplated, zero magnetostrictive Co90Fe10(wt%) alloy thin film has a very high saturation moment (Bs=19 KG) and fairly good soft magnetic properties, which appears to make it a potential replacement for permalloy as pole material in high density longitudinal and perpendicular recording. The magnetic properties of CoFe thin films were investigated. Thin film heads using CoFe-as the pole-piece material were fabricated and evaluated using 5-1/4 inch sputtered CoNiCr thin film disks with Hc= 1000 Oe, Br= 9,000 Gauss and a 300 A thick overcoat. -45 dB overwrite was achieved with 0.2 micron head-disk spacing.
