Preparation, properties and applications of magnetic nanoparticles [PDF]

Beilstein Journal of Nanotechnology, 2010
Though studies on small particles of various materials go way back before Nanoscience was emerging, this new interdisciplinary branch of science not only re-termed them into nanoparticles (NPs), but also lead to a dramatically enhanced interest in this type of nanoscaled material with an often given though arbitrary upper diameter limit of 100 nm [1 ...

Preparation and Properties of Various Magnetic Nanoparticles [PDF]

Sensors, 2009
The fabrications of iron oxides nanoparticles using co-precipitation and gadolinium nanoparticles using water in oil microemulsion method are reported in this paper. Results of detailed phase analysis by XRD and Mössbauer spectroscopy are discussed. XRD analysis revealed that the crystallite size (mean coherence length) of iron oxides (mainly γ-Fe2O3 ...

Magnetic and Electrical Properties of CuCr2Se4 Nanoparticles

Materials, 2023
CuCr2Se4 nanoparticles were obtained by the high-energy ball milling of CuCr2Se4 single crystals, which had a size of approximately 32 nm after 5 h of milling. Structural, magnetic, and electrical studies have shown that a reduction in CuCr2Se4 single crystals to the nanosize leads to (1) a weakening of ferromagnetic interactions, both long and short ...

Magnetic Properties of Fe-Doped Nio Nanoparticles

Heliyon, 2023
Undoped and Fe-doped NiO nanoparticles were successfully synthesized using a lyophilization method and systematically characterized through magnetization techniques over a wide temperature range, with varying intensity and frequency of the applied magnetic fields. The Ni1-xFexO nanoparticles can be described by a core-shell model, which reveals that Fe

Magnetic Nanoparticles: The Simulation of Thermodynamic Properties [PDF]

, 2007
Magnetic materials are now controllable down to a nanometer length scale and, hence, there is a broad interest in the understanding of magnetic phenomena in nanostructured systems. With decreasing size thermal activation becomes more and more relevant and the understanding of the role of temperature for the dynamic behavior and for the magnetic ...

Magnetic nanoparticles: From the nanostructure to the physical properties

Journal of Magnetism and Magnetic Materials, 2022
Some of the synthesis methods and physical properties of iron-oxide based magnetic nanoparticles such as Fe3-xO4 and CoxFe3-xO4 are reviewed because of their interest in health, environmental applications, and ultra-high-density magnetic recording. Unlike high crystalline quality nanoparticles larger than a few nanometers that show bulk-like magnetic ...
