Ce-Doped Manganites of Lanthanum-Strontium as Promising Inducers of Magnetic Hyperthermia

Ce-doped nanoparticles of La-Sr manganite were synthesized via sol-gel method. Formation of the single-phased nanoparticles with the perovskite structure up to 5% of Ce was studied by X-ray diffraction method. Magnetic properties of obtained manganite nanoparticles were investigated. It was found that magnetic fluids based on the obtained nanoparticles heated up effectively under the action of an alternating magnetic field to 43-45°C.
