چکیده:

In the present work, the effect of Dy3+ substitution on the structural and magnetic properties of Co1-xDyx Fe2O4 (x=0, 0.01, 0.03, 0.05, 0.1) system prepared by co precipitation method were investigated. The phase purity and crystal lattice symmetry were estimated from X-ray diffraction studies. Transmission electron microscope micrograms showed the 15nm size nanoparticles. Room temperature magnetization measurements showed that the saturation magnetization and hysteresis losses (coercivity) were changed with Dy3+ addition
