Title:
NICKEL-IRON ALLOY PLATING SOLUTION
Document Type and Number:
WIPO Patent Application WO/2011/062031
Kind Code:
A1
Abstract:
The disclosed nickel-iron alloy plating solution contains divalent iron ions and divalent nickel ions, suppresses that oxidation of divalent iron ions into trivalent iron ions, can prevent the occurrence of an iron (III) hydroxide precipitate, can be used in performing a stable continuous operation, and can obtain a soft magnetic film having a stable composition. The nickel-iron alloy plating solution is characterized by containing divalent iron ions, divalent nickel ions, and a hydroxylamine salt, and by having a pH of no more than 3.0.
