Induced effects of Zn+2 on the transport and complex impedance properties of Gadolinium substituted nickel-zinc nano ferrites

•Gd substituted Ni-Zn nanoferrites were synthesized via Low-temperature citrate precursor method.•Rietveld refinement suggests the formation of a good nanocrystalline phase in the samples.•Maximum dielectric constant with a minimum dielectric loss obtained for x = 0.4 and y = 0.1.•With the increase...
