Effect of electric field on the dielectric and magnetic properties of random nanocomposites

In this work, dielectric and magnetic properties of Ag/Zr0.9Ni0.1Oy nanocomposite subjected to an ac electric field were investigated. We showed that with the application of ac electric field with a quadrupole electrode, Ag nanowires can be efficiently driven to align, to the chain in parallel directions. The morphology and structure properties of Ag/Zr0.9Ni0.1Oy nanocomposite were studied by X-ray diffraction (XRD), scanning electron microscopy (SEM) and transmission electron microscopy (TEM) techniques. The permittivity and permeability measurements showed that the sample subjected to an ac electric field for 8 s was a promising candidate for the double negative materials (DNMs).
