Abstract

Slightly agglomerated, crystalline nanoparticles of ferromagnetic compounds with spinel and perovskite La_1-xSr_xMnO₃ structure have been synthesized by the sol-gel method, precipitation from glycol solutions and using microemulsion technique. “Core/shell” La_1-xSr_xMnO₃/SiO₂ structure have been developed. Magnetic properties of the synthesized nanoparticles have been investigated. It was shown that the obtained nanoparticles exhibit superparamagnetic properties. It has been found that the synthesized nanoparticles have promise in hyperthermia of cancer cells.
