  • Method for electrodeposition of ferromagnetic alloys and article made thereby
    Patent number: 3950234
    Abstract: An electrolytic plating solution and method for depositing ferromagnetic recording films therefrom is described. The plating solution has cobaltous ion in the range of from about 3 to 15 grams per liter, nickelous ion in the range of from about 30 to 50 grams per liter, and orthophosphite ion in the range of from about 3 to 12 grams per liter. It is important that the ratio of nickelous ions to cobaltous ions be in the range of from about 3:1 to about 15:1. The plating solution is substantially free of hypophosphite ion, phosphate ion, copper and iron so that phosphite ion is the sole source of phosphorus. Optionally the solution may contain up to about 30 grams per liter of boric acid and up to about 25 grams per liter of formate ion. The pH of the solution is maintained in the range of from about 3.5 to 4.7.
