The paper focuses on the electrical, magnetical and morphology characterization of Ag/Zr0.9Ni0.1Oy (AZNx) nanostructures with different atomic ratios “x” (where “x” is 0, 5, and 25%). The structure and morphology properties of the AZNx nanostructures were evaluated by x-ray diffraction (XRD), scanning electron microscopy (SEM) techniques. Here, a negative permittivity behavior of AZN25% is found. Furthermore, the experimental data of the plasma-like negative permittivity are fitted well by a lossy Drude model, suggesting the plasma frequency of 6.78 GHz (x = 25%).The complex permeability of AZN25% presents negative susceptibility ( e ' < 1). These results have important implications for the realization of double negative properties in single-phase LSMO as a promising candidate for the DNMs.
