摘要
Soft magnetic CoFeCr films produced with high saturation magnetic flux density, B-s = 1.7 T, low coercivity, H-c = 0.6 Oe, and high film resistivity, p = 40 M cm, are potentially useful in high density magnetic recording head. The electrodeposition of CoFeCr ternary alloy is investigated in the presence of two sulfur containing organic additives, saccharin (SAC) and o-toluene sulfonamide (oTOL). The results demonstrated that the CoFeCr films produced with SAC or oTOL have the same structural and magnetic properties. However, a corrosion behavior study shows that the CoFeCr deposits prepared with oTOL are very attractive for their stability in corrosive conditions. This additive (oTOL) can be considered as a good candidate for electroplated soft magnetic CoFeCr films. (C) 2003 Elsevier B.V. All rights reserved.
