The frequency dependence of magnetic heating for La^sub 0.75^Sr^sub 0.25^MnO^sub 3^ nanoparticles

The frequency dependence of magnetic heating for La^sub 0.75^Sr^sub 0.25^MnO^sub 3^ nanoparticles

The study addresses the role of frequency of the AC magnetic field on heating of La0.75Sr0.25MnO3 nanoparticles. We observe (i) a superlinear dependence of specific absorption rate as a function of frequency at the body temperature and (ii) the presence of a maximum temperature at which the magnetic...

Zusammenfassung:The study addresses the role of frequency of the AC magnetic field on heating of La0.75Sr0.25MnO3 nanoparticles. We observe (i) a superlinear dependence of specific absorption rate as a function of frequency at the body temperature and (ii) the presence of a maximum temperature at which the magnetic heating stops. This self-limiting mechanism of the magnetic heating can be used in various applications such as magnetic fluid hyperthermia or catalysis.
