Synthesized core / shell nanostructures of (La, Sr) MnO3/SiO2 method of layering and "direct deposition" SiO2 to weakly agglomerated particles substituted lanthanum manganite (La, Sr) MnO3. Microstructural studies conducted core / shell structures synthesized by thermal treatment at different temperatures (200-800 ° C) and determined that the amount of SiO2 deposited layers are in the range of 5-10 nm, depending on the method of synthesis The magnetic properties of weakly agglomerated nanoparticles (La, Sr) MnO3 and core / shell nanostructures (La, Sr) MnO3/SiO2. Shown that they are characterized by a low coercivity and exhibit properties similar to superparamagnetic. Developed a magnetic fluid based on weakly agglomerated nanoparticles (La, Sr) MnO3 and the core / shell structures (La, Sr) MnO3/SiO2 and aqueous solutions of agarose. It is shown that by the magnetic fluid heated by the electromagnetic field to the desired temperature, the size of which can be controlled by changing the chemical composition of ferromagnetic nanoparticles. Results of the research of the magnetic properties can be considered synthesized core / shell structure as a potentially promising inducers hyperthermia of deep-seated tumors and require further research.
