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 8s was a promising candidate for the double negative materials (DNMs).
