Abstract: We report on the suitability of core/shell nanoparticles (NPs) for magnetic fluid hyperthermia in a selfregulated and theranostic approach. Aqueous magnetic colloids based on core/shell ZnxMnyFezO4@γ-Fe2O3 and ZnxCoyFe-zO4@γ-Fe2O3 NPs were produced by a three-step chemical synthesis. Systematic deviations from stoichiometry was observed with increasing Zn substitution for both series of samples. We investigated how the chemical composition affects saturation magnetization, magnetic anisotropy and thermomagneti… Show more

“…Due to the different extrinsic parameters used for the calculating of SAR, it is hard to compare our results with the ones obtained by other researchers. For instance, Pilati et al synthesized Zn–Mn and Zn–Co ferrites as thermosensitive heat sources and showed that SAR could increase from 100 W/g to more than 400 W/g by increasing frequency from 265 to 831 kHz. They also reported that the amplitude of magnetic field plays a decisive role in the SAR value.…”

“…Due to this and achieving various properties such as magnetic permeability, coercive force, anisotropy constant, saturation magnetization (Ms), mechanical stiffness, physical and chemical stability, the range of use of these materials is varied. Accordingly, much research has been done on the doping effect of different 2/3 valent elements inside the ferrite structures on the synthesis and magnetic properties [5][6][7][8][9][10][11][12][13][14][15]. Among them, cobalt ferrite is interested due to properties such as high magnetic permeability, high coercive force (HC) (≥50 KOe), good saturation magnetization (MS) (80 emu/gr), mechanical hardness and excellent physical and chemical stability.…”

“…Thus, NSFs have found a considerable amount of use in environmental, biomedical, industrial and technological applications including magnetic resonance imaging microwave absorbers, contrast agents, catalysts, drug delivery agents, magnetic storage devices etc. [1][2][3][4][5][6][7][8][9] Ni-Cu-Zn ferrite is a spinel ferrite mainly used in multi-layer chip inductors (MLCIs). 10 MLCIs are mainly used in mobile phones, notebook computers and video cameras.…”
