Abstract
The work is devoted to the development of hybrid materials for medical hyperthermy based on carbon nanotubes (CNTs) modified in their internal channels by perovskite-like manganites. It is shown that phases are formed in preliminarily opened channels of tubes from precursors: salts, manganese, strontium, calcium and lanthanum carbonates and oxides. High-resolution transmission electron microscopy reveals fine crystalline particles of complex oxide phases inside the CNTs, and reflections corresponding to the temperature of the solid-phase synthesis of manganites are found on the calorimetric dependences.
