Structural, optical and magnetic properties of Fe3O4 nanoparticles prepared by a facile microwave combustion method

Magneto Optical Properties of FeBxFe2−xO4 Nanoparticles

“…The bigger E g value of NPs prepared by co-precipitation method is attributed to the smaller particle size of 20 nm. Similarly, in another research performed by Manikandan et al [3,23], the particle size effect is attributed as the reason to detect bigger E g values of 2.12 eV from the Fe 3 O 4 NPs (with sizes of 20-25 nm) prepared by facile microwave combustion method [4]. They reported that the band gap decreased to 2.05 eV when the particle size increased to a range of 30-35 nm.…”

“…Magnetic NP and nano ferrite like hematite, metal ferrites and magnetite are largely used in the different field of catalysts and biomedicine, like enzyme and protein immobilization, drug delivery bioseparation, magnetic resonance imaging (MRI) because of their anisotropic magnetic and optical properties [1][2][3], water treatment and etc [4]. Magnetic metal oxides, Fe 3 O 4 has many advantages with twist electromagnetic properties and several important applications in ferrofluids, MRI, hyperthermia treatment, magnetic storage media, manipulating cell membranes because of its high values of magnetic saturation [5,6].…”

Effect of Fe-doping on the structural, optical and magnetic properties of ZnO nanostructures synthesised by co-precipitation method

“…The crystal anisotropy and shape anisotropy may be responsible for such low value of saturation magnetization. It was already reported that size factor, crystallinity and surface structure have great influence on the evolution of magnetic properties of materials [30].…”

Research on the Preparation and Characterization of Magnetic Nanoparticles (MNPs) By Chemical Co-precipitation

“…[1][2][3][4][5], and in special catalytic materials, magnetic pigment, but also has a great purpose in drug synthesis, what is more important in medical equipment, biological medicine uses more and more intensively. The high temperature radio frequency (RF), magnetic resonance imaging, medical diagnosis, cancer therapy and so on is involved in its application [6][7][8][9].…”

“…Physical methods mainly refer to mechanical polishing method; Chemical methods are including hydrothermal method, co-precipitation method, microemulsion method, sol-gel method, nonaqueous solvent synthesis method, high temperature pyrolysis method, etc. [8]. The chemical precipitation method was adopted in this paper, the characterization and the various factors on the properties of nano magnetic ferroferric oxides were explored.…”
