We have synthesized, physically characterized and tested coated ferromagnetic manganese perovskite particles. SiO2 coating minimizes toxicity in cell cultures and the particles can be used as cellular labels for guided termoablation. Ferromagnetic particles can be heated by external high frequency electromagnetic field. Thermoablation is self-controlled due to low Curie temperature, the material cannot be heated to temperature over Tc.
