Claim:
1. A method for forming an on-chip magnetic structure, the method comprising: activating a magnetic seed layer with a palladium solution to form a palladium-activated magnetic seed layer, the magnetic seed layer being positioned over a semiconductor substrate; and electrolessly plating a magnetic alloy onto the palladium-activated seed layer to form an amorphous soft magnetic layer; wherein the amorphous soft magnetic layer comprises nickel in a range from about 50 to about 80 at. % based on the total number of atoms of the magnetic material, iron in a range from about 10 to about 50 at. % based on the total number of atoms of the magnetic material, and phosphorous in a range from about 0.1 to about 30 at. % based on the total number of atoms of the magnetic material.
