  • Abstract
    The authors investigated the method of preparation and soft magnetic properties of electrodeposited Fe-Co-Ni-Cr alloy film with high saturation magnetization and a single-phase structure. It was found that Fe-Co-Ni-Cr alloy film with a single-phase fcc structure can be electrodeposited at the cathode in a solution composed of Fe2+, Co2+, Ni2+ and Cr3+ ions and with SO42- as the count anion, by plating at current densities of more than 30 mA/cm2. Film consisting of Fe44Co17Ni36Cr3 alloy, prepared by the plating method described in this paper, has soft magnetic properties (¿iHA ≫ 1500, HcHA ≪ 0.5 Oe, ¿s = 6x10-6, Bs = 16,800 G) qualifying it for use in HDD thin film magnetic head cores.
