An electrodeposited CoNiFe soft magnetic thin film with Bs as high as 20-21 kG is very attractive as a candidate for write head core materials, meeting the demand for increasing magnetic recording density. We developed electrolessly deposited CoNiFe-based soft magnetic thin films with 18-19 kG of Bs and 30 μΩcm of resistivity. This thin film formation method has the advantage of fabricating smaller and finer head cores, which can realize higher recording density compared with conventional techniques of fabricating head cores. For higher-frequency recording, the electroless CoNiFeB film should have higher resistivity whilst keeping high Bs for suppressing eddy-current losses. Therefore, we investigated increasing the resistivity of high Bs CoNiFeB soft magnetic thin films prepared by electroless deposition.
