  • Abstract
    In this work we have studied the magnetic properties of room temperature electrodeposited Cu2O layers doped with Co. These layers showed anhysteretic ferromagnetic behavior with Curie temperature of 550 K. Structural characterization indicated the incorporation of Co+2 ions to the Cu2O lattice. No evidences for the existence of superparamagnetic particles and contaminations were observed, respectively, from (zero field cooling) ZFC and (field cooling) FC curves and (electron paramagnetic resonance) EPR measurements.
