摘要：

In the present work, cobalt ferrite and Zn-doped cobalt ferrite nanoparticles were synthesized using a low temperature solution method. A study of the magnetic properties of the CoFe2O4 nanoparticles shows high coercivity at 10 K. Co0.5Zn0.5Fe2O4 nanoparticles show a lower coercive field but a higher saturation magnetization as compared to CoFe2O4 nanoparticles. Blocking temperature of the particles decreased from 355 K for CoFe2O4 to 220 K for Co0.5Zn0.5Fe2O4. A PbZr0.52Ti0.48O3:CoFe2O4 composite film prepared using CoFe2O4 nanoparticles dispersed in PbZr0.52Ti0.48O3 solution shows ferroelectric and ferromagnetic properties. Such low-cost synthesis approach shows promise for use in magnetoelectric composite films.
