Patent ID: 8118990

Claim:
A method to deposit through electrodeposition a layer having magnetic properties that include both a coercivity less than 0.3 Oe and a saturation magnetization of at least 24 kG, consisting of: providing a plating bath that consists of, in solution, nickel in a concentration range of from 0-70 g/L, iron in a concentration range of from 25-120 g/L and cobalt in a concentration range of from 10-60 g/L, as well as H 3 BO 3 , NaCl, a surfactant, and aryl sulfinates in a concentration range of from about 0.05 to 0.3 g/L; and then electrodepositing said layer from said plating bath, with no subsequent heat treatment, whereby said layer, as deposited, has said magnetic properties.
