摘要: The role of agglomeration and magnetic interparticle interactions in heat generation ferrofluids an ac field is still unclear, with apparent discrepancy between the results presented literature. In this work, we measured generating capability agglomerated ferrite nanoparticles a non-invasive f = 100 kHz H0 13 kA m −1 . were morphologically magnetically characterized, specific absorption rate (SAR) for our presents clear dependence on diameter nanoparticles, maximum SAR 48 Wg 15 nm. Our have large hydrodynamic diameters, thus mechanical relaxation can be neglected as mechanism. Therefore, present model that simulates samples based hysteresis losses valid non-linear region (with comparable to anisotropy field). takes into account among agglomerate. For comparison, also non-agglomerated similar range, which N´ eel Brown relaxations dominate generation. (Some figures may appear colour only online journal)
