Abstract: A method includes immersing a wafer in an electrolyte including a plurality of compounds having elements of a high damping magnetic alloy with very low impurity and small uniform grain size. The method also includes applying a pulsed current with a certain range of duty cycle and pulse length to the wafer when the wafer is immersed in an electrolyte. The wafer is removed from the electrolyte when a layer of the high damping magnetic alloy is formed on the wafer.
