nanoparticles of mn0.5zn0.5-xcdxfe2o4 with x varying from x = 0.0 to 0.3 were prepared by wet chemical co-precipitation method. the structural and magnetic properties were studied by using x-ray diffraction (xrd), scanning electron microscope (sem), transmission electron microscopy (tem) and electron paramagnetic resonance (epr) technique. the lattice constant increases with increase in cd cont...
