Abstract
Ni1-xZnxFe2 O-4 (0.0 less than or equal to x less than or equal to 1.0) nan oparticles have been prepared by the polyvinyl alcohol (PVA) sol-gel method . The lattice parameter of Ni-Zn nanoparticle is larger than that of the bu lk material. The Mossbauer spectra of the samples showed the presence of ul trafine particles exhibiting superparamagnetic relaxation at room temperatu re and an ordered magnetic structure at 77 K.
