Claim Text:
1. A method for forming an on-chip magnetic structure, the method comprising: activating a magnetic seed layer with palladium, the magnetic seed layer being positioned over a semiconductor substrate; and electrolessly plating a magnetic alloy onto the palladium to form a Pd/CoWP layer; wherein the Pd/CoWP layer comprises cobalt in a range from about 80 to about 90 at. % based on the total number of atoms of the magnetic material, tungsten in a range from about 4 to about 9 at. % based on the total number of atoms of the magnetic material, phosphorous in a range from about 7 to about 15 at. % based on the total number of atoms of the magnetic material, and palladium substantially dispersed throughout the magnetic material.
