摘要: We present a versatile diagram to envisage the dominant relaxation mechanism of single-domain magnetic nanoparticles (MNPs) under alternating fields, as those used in fluid hyperthermia (MFH). The allows estimating heating efficiency, measured by Specific Power Absorption (SPA), originated and viscous times MNPs for given frequency ac field (AFM). has been successfully applied different colloids, covering wide variety with anisotropy particle size, dispersed liquid carriers. From general diagram, we derived specific chart based on Linear Response Theory order easily estimate experimental condition optimal SPA values most colloids currently MFH.
