Optical, magnetic and electrical investigation of cobalt ferrite nanoparticles synthesized by co-precipitation route

NMR Relaxation of Water in Nanostructures: Analysis of Ferromagnetic Cobalt-Ferrite Polyelectrolyte Nanocomposites

“…48.4 emu g À1 ) are somewhat lower than the literature values for similar cobalt ferrite nanoparticles (e.g. 61.5 emu g À1 ), [16] but comparable with the magnetisation of typical biopolymermagnetite nanocomposites (40-50 emu g À1 ), which can be used for MRI and drug delivery. [17] The samples were further characterised structurally by transmission electron microscopy (TEM) and photon correlation spectroscopy (PCS).…”

Microstructure and characterization of a novel cobalt coating prepared by cathode plasma electrolytic deposition

“…This is different from the conventional electrodeposition or chemical plating process, because the Co coatings prepared by conventional methods are always with hcp structure. They need to be treated with annealing to be transformed into fcc structure in some cases, in order to improve their dielectric and soft magnetic properties [50,51]. It is complicated and inconvenient.…”

Influence of Cr<sup>3+</sup> Ion on the Dielectric Properties of Nano Crystalline Mg-Ferrites Synthesized by Citrate-Gel Method

“…According to this, dielectric material has well conducting grains separated by highly resistive grain boundaries. On the application of electric field, space charge accumulates at the grain boundaries and voltage drops mainly at grain boundaries [16]. Koops proposed that grain boundary effect is more at low frequencies [16].…”

“…On the application of electric field, space charge accumulates at the grain boundaries and voltage drops mainly at grain boundaries [16]. Koops proposed that grain boundary effect is more at low frequencies [16]. As the frequency increased beyond a cer- and Fe 3+ ions results in local displacement of electrons in the direction of applied field that determines polarization.…”
