NiFeCu alloy films were electrodeposited from baths containing nickel sulfate and/or nickel sulfamate. All samples were pulse plated in the potentiostatic mode. The room temperature magnetoresistances of the films were measured showing anisotropic magnetoresistances up to 1.5%. The anisotropic magnetoresistances increased with the addition of sulfamic acid to the sulfate bath. Samples deposited from the bath with high sulfamate concentration showed a giant magnetoresistance behavior. To characterize the films, scanning electron microscopy and X-ray diffraction were used.
