Abstract:
An on-chip magnetic structure includes a magnetic material comprising cobalt in a range from about 80 to about 90 atomic % (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.
