Patent ID: 8303794

Claim:
A method of forming a layer of a magnetic material, which has vertical magnetic properties, the method comprising: forming the layer of the magnetic material by electroplating the magnetic material onto a substrate in an eletrochemical bath which contain colbalt, nickel, rhenium, phosphorus, and platinum; wherein the electroplating includes electrochemically depositing the cobalt, nickel, rhenium, phosphorus, and platinum onto the substrate so as to form the layer of the magnetic material on the substrate, the layer of magnetic material comprising: 50-80 wt % of Colbalt; 9-15 wt % of Nickel; 10-25 wt % of Rhenium; 0.1 to 2.0 wt % of Phosphorus; and 5-10 wt % of Platinum.
