Structural and magnetic properties of nano-crystalline Ag+ doped NiFe2O4

Ni ferrite nanoparticles were prepared using citrate method. XRD pattern revealed the formation of the samples as synthesized in the spinel cubic structure. Silver doping effect on the magnetic properties of Ni ferrite was investigated. The lattice parameter was slightly increased while the values of the Curie temperature decreased with increasing Ag content. The magnetic susceptibility was measured using Faraday’s method and the calculated magnetic constants were reported. The data showed that χM and effective magnetic moment decrease with increasing Ag content.
