Giant magnetoresistance (GMR) and ferromagnetic properties of DC and pulse electrodeposited Cu-Co alloys

► Evidence of multiple ferromagnetic phases identified with particles of disparate morphology and ferromagnetic features. ► Ferromagnetic resonance spectra of Cu-Co electrodeposits are suitably correlated with magnetoresistance properties. ► Frequency of pulse electrodeposition and size of magnetic particles seems to hold key on GMR values.
