For many medical applications related to diagnosis and treatment of cancer disease, hyperthermia plays an increasingly important role as a local heating method, where precise control temperature parameters the working material is strongly required. Obtaining smart with "self-controlled" in desirable range relevant task. this purpose, nanopowder manganite perovskite super-stoichiometric manganese has been synthesized, which consists soft spherical-like ferromagnetic nanoparticles average size 65 nm narrow magnetic phase transition at 42 °C. Based on analysis experimental data, specific loss power calculated for both quasi-stable relaxation hysteresis regions. It shown that cell structures °C may occur short time (∼1.5 min.) Upon reaching °C, stopped due paramagnetic state. The obtained results demonstrate possibility using synthesized nanomaterial automatic stabilization safe without risk mechanical damage structures.
