摘要：
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 degrees C without external temperature control. Termination temperatures of manganite suspensions are close to T-c and demonstrate, unlike other proposed mediator materials, a negligible dependence on the concentration of mediator particles in suspension.
