Hollow microspheres of Ce3+ doped NiCo-ferrites were synthesized by template-based-deposition and surface reaction method.
The influence of rare earth Ce3+ on the magnetic and absorbing properties of sample was studied.
When the content of Ce was 0.02, the maximal saturation magnetization value and coercivity was 75.72 emu•g−1 and 789.88 Oe, respectively.
