TL;DR: In this paper, the influence of particle chain formation on the normalized heating properties, or specific loss power (SLP) of both low-spherical and high-parallelepiped anisotropy ferrite-based magnetic fluids was explored.

TL;DR: Analysis of ferromagnetic resonance data shows that high particle concentrations correlate with increasing chain length producing decreasing SLP, and a theoretical model describing dipole interactions valid for the linear response regime is proposed, predicting optimum particle sizes for hyperthermia to about 30% smaller than those previously predicted, depending on the nanoparticle parameters and chain size.

TL;DR: In this paper, the role of magnetic anisotropy on the specific absorption rate of cobalt-ferrite nanoparticles with diameters ranging from 3 to 14 nm was discussed.

TL;DR: In this article, a chemical core−shell strategy is developed for the synthesis of ferrofluids based on nanoparticles of different ferrites with different mean sizes, which is tested by chemical and magnetic measurements performed at the various steps of the synthesis.
