Investigation of structural, magnetic and dielectric properties of Mo-doped ZnCu2Nb2O8
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.We have studied structural,magnetic and dielectric properties of Mo-doped ZnCu2Nb2O8 with Mo replacing Nb ion.
