Abstract
We have studied structural,magnetic and dielectric properties of Mo-doped ZnCu2Nb2O8 with Mo replacing Nb ion. Here we have prepared polycrystalline samples ZnCu2(Nb1-x Mox)2O8 with x=0.0 and 0.1. X-ray powder diffraction and allied Rietveldrefinement analysis have been used to analyze the structure of the samples. The ZnCu2Nb2O8 shows paramagnetic behavior in whole temperature range. In ZnCu2Nb2O8, Nb+2(S=0) is a non-magnetic site, we have tried to tune the non-magnetic site with magnetic Mo+2(S=1/2). With Mo substitution at Nb-site, magnetic moment decreases and the system remainin paramagnetic state in whole temperature range. Effect of Mo doping shows a structural change in lattice parameters while there is no change in electrical properties as well as in magnetic properties. Frequency dependent dielectric measurement has been done at room temperature.
