Abstract

La?Ag and La?Na perovskite manganites could be considered as smart mediators for various biomedical applications requiring self-controlled isothermal heating including magnetic hyperthermia. Dissipation of the alternating magnetic field energy causes heating of their aqueous suspensions to terminate at 42?48??C without external temperature control. Termination temperatures of manganite suspensions are close to Tc and demonstrate, unlike other proposed mediator materials, a negligible dependence on the concentration of mediator particles in suspension.
