Figure 4From: The influence of colloidal parameters on the specific power absorption of PAA-coated magnetite nanoparticles Evolution of the specific absorption rate (SAR) of Fe 3 O 4 @PAA NPs dispersions with solvent viscosity, η, under an external AC magnetic field of B = 15 mT and ν = 308 kHz. Solid line is a guide for the eye.Back to article page
