Magnetic particle hyperthermia, in which colloidal nanostructures are exposed to an alternating magnetic field, is a promising approach cancer therapy. Unfortunately, the clinical efficacy of hyperthermia has not yet been optimized. Consequently, routes improve such as designing hybrid structures comprised different phase materials, actively pursued. Here, we demonstrate enhanced efficiency relatively large spherical Fe/Fe-oxide core–shell nanoparticles through manipulation interactions...
The study presented in this work consists of two parts: first part is the synthesis Graphene oxide-Fe3O4 nanocomposites by a mechanochemical method which, mechanical process that likely to yield extremely heterogeneous particles. second includes on efficacy these kill cancerous cells. Iron powder, ball milled along with graphene oxide toluene medium, underwent controlled oxidation process. Different phases GO-Fe3O4 were obtained based composition used for milling. As synthesized...
Mixed ferrite nanoparticles with compositions CoxMn1-xFe2O4 (x = 0, 0.2, 0.4, 0.6, 0.8, and 1.0) were synthesized by a simple chemical co-precipitation method. The structure morphology of the obtained X-ray diffraction (XRD), transmission electron microscope (TEM), Raman spectroscopy, Mössbauer spectroscopy. average crystallite sizes decreased increasing x, starting 34.9 ± 0.6 nm for MnFe2O4 0) ending 15.0 0.3 CoFe2O4 1.0). TEM images show an edge majority particles having cubic geometry...

Magnetically hard–soft core-shell ferrite nanoparticles are synthesized using an organometallic decomposition method through seed-mediated growth. Two sets of (S1 and S2) with different shell (Fe3O4) thicknesses similar core (CoFe2O4) sizes obtained by varying the initial quantities seed size 6.0 ± 1.0 nm.

Magnetically soft-soft MnFe2O4-Fe3O4 core-shell nanoparticles were synthesized through a seed-mediated method using the organometallic decomposition of metal acetyl acetonates. Two sets (S1 and S2) similar core sizes 5.0 nm different shell thicknesses (4.1 for S1 5.7 obtained by changing number nucleating sites. Magnetic measurements conducted on at low room temperatures to study thickness temperature dependence magnetic properties. Interestingly, both showed saturation magnetization,...
Fe 65 Co 35 /underlayer bilayer films were successfully prepared on different underlayer materials (Co93Fe7, Ni80Fe20, Cu, and Fe). The soft magnetic properties of Fe65Co35 improved when the texture changed from (110) to (200), which can be controlled by underlayers. conversion electron Mössbauer spectroscopy revealed that angle between effective magnetization normal direction with is smaller than (200) texture. Calculations confirmed total anisotropy energy density film larger Therefore,...
In this paper we study the structural, morphological and magnetic properties of La0.67Sr0.33MnO3 (LSMO) manganite nanoparticles (NPs) its biocomposite, obtained by mixing NPs hydroxyapatite (HA). From studies X-ray diffraction Fourier transmission infrared spectroscopy it is evident that in biocomposite sample both individual phases are distinguishable from each other. The measurements direct current (DC) magnetization hysteresis loops reveal basic behaviour LSMO–HA similar to LSMO; however,...
