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.

Abstract: A method includes immersing a wafer in an electrolyte including a plurality of compounds having elements of a thermally stable soft magnetic material. The method also includes applying a combined stepped and pulsed current to the wafer when the wafer is immersed in an electrolyte. The wafer is removed from the electrolyte when a layer of the thermally stable soft magnetic material is formed on the wafer.

Abstract: A method of forming a magnetic recording head. The method includes depositing a sacrificial metal alloy layer, which is wet etchable and has a moderate mill resistance, over a substrate. The method also includes depositing a write pole layer over the sacrificial metal alloy layer. The write pole layer has a bottom surface and a top surface opposite the bottom surface. A portion of the bottom surface of the write pole layer is in contact with the sacrificial metal alloy layer.
