Structural and magnetic properties of free-standing Ni0.23Cu0.11Zn0.66Fe2O4 thick films prepared using a modified tape-casting method

Free-standing Ni0.23Cu0.11Zn0.66Fe2O4 thick films have been prepared using a modified tape-casting method from a viscous paint. The surface morphology, saturation magnetization (Ms), coercivity (Hc) and complex permeability of the thick films were studied. It is demonstrated that the thick films have relatively larger complex permeability and higher resonance frequency as compared to their bulk material counterparts.
