Abstract

PURPOSE: To raise the magnetic characteristics by forming the noncrystalline alloy- plated layer containing a given ratio of Co and P as the main components.
CONSTITUTION: In the place of Fe-P noncrystalline alloy previously applied, a Co- P noncrystalline alloy-plated layer, containing 60W92atom% Co and 8W26atom% P as the main components, is obtained by an electric plating method using an acid plating bath consisting primarily of approx. 1/6W3mol/l of a divalent Co ion (e.g., cobalt sulfate, etc.) and approx. 0.03W0.3mol/l of hypophosphic acid and/or a hypophosphite (e.g., sodium hypophosphite, etc.). The conditions for plating includes pH1.2W2.2, a current density of 5W20A/dm2, and a bath temperature of 30W60°C, and also a stabilizer, e.g., L-ascorbic acid, etc., and a brightener, e.g., hydroquinolic acid, etc., are added to the plating system. Thus, a magnetostriction constant is made smaller and also magnetic permeability and coercive force are raised.
