Magnetic Characterization of Co Doped Cu$_{2}$O Layers

In this work we have studied the magnetic properties of room temperature electrodeposited Cu
₂
O 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 Cu
₂
O 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.
