La- and Ni-doped Fe3O4 nanocomposite particles with a high saturation magnetization were prepared by a homogeneous precipitation method in aqueous solutions. The obtained nanoparticles were characterized by X-ray diffraction (XRD), transmission electron microscopy (TEM), inductively-coupled plasma atomic emission spectroscopy (ICPAES) and vibrating sample magnetometry (VSM). The results showed the diameters of La- or Ni-doped Fe3O4 composite particles to be in the range of 10-25 nm. The specific saturation magnetization of La- or Ni-doped Fe3O4 was considerably higher than that of pure Fe3O4 nanoparticles. The nanocomposite particles exhibited superparamagnetic behaviour.
