Dependence of specific absorption rate on concentration of Fe3O4 nanoparticles: from the prediction of Monte Carlo simulations to experimental results
Specific absorption rate (SAR) of magnetic iron oxide (Fe 3 O 4 ) nanoparticles (NPs) is an important property in hyperthermia applications. In this work, the dependence of magnetic anisotropy ( K ) on concentration of Fe 3 O 4 NPs has been investigated using the Monte Carlo simulations. The results...
