Abstract

Illustration of the variation of SAR and ILP values with different concentrations for ac magnetic fields of amplitude H = 161 G and H = 226 G.

RETRACTED ARTICLE: A comprehensive scrutiny to controlled dipolar interactions to intensify the self-heating efficiency of biopolymer encapsulated Tb doped magnetite nanoparticles

“…Based on the magnetic findings (Fig. 14 ), it has been observed that the saturation magnetization is relatively high for CTbFO MNPs than DTbFO MNPs, suggesting that this likely contributes to the improved heating efficiency 66 . Henceforth, these results have empirical consequences for MFH optimization.…”

Dextran-coated nanoparticles as immunosensing platforms: Consideration of polyaldehyde density, nanoparticle size and functionality

“…S1B), and the saturation magnetization of bare NPs decreased from 84 to 46 emu g Fe − 1 upon the dextran grafting. This reduction confirms the presence of dextran (non-magnetic material), the partial oxidation of magnetite to maghemite in the coating process (accounts for a reduction in saturation magnetization of ~ 10%) and also some surface spin disorder at the nanoparticles magnetic surface [31] (Fig. 1C).…”

Role of site selective substitution, magnetic parameter tuning, and self heating in magnetic hyperthermia application: Eu-doped magnetite nanoparticles

“…15 . 52 Herein, the replacement of Eu cations with Fe ions enhances the magnetocrystalline anisotropy, which can be noticed from the above-mentioned respective graph and can be the reason for the improved self-heating properties (SAR). 53 Furthermore, in light of VSM analysis suggesting that MNPs are nearly superparamagnetic, relaxation losses (Brownian & Néel relaxation loss) govern the heat generation mechanism rather than Hysteresis loss.…”
