Magnetic and dielectric properties of polymer-coated Ni0.5Co0.3Cu0.2Fe2O4 nanostructures

Ni0.5Co0.3Cu0.2Fe2O4 and Ni0.5Co0.3Cu0.2Fe2 O4/polyethylene glycol (PEG) were synthesized by using the co-precipitation method. The structural, morphological, magnetic, and dielectric properties of the products were characterized by X-ray diffraction (XRD), Fourier transform infrared spectroscopy (F...
