Magnetic properties of La2NiMnO6 nanoparticles

AIP Conference Proceedings, 2012
La2NiMnO6 nanopaticles with an average particle size ∼ 27nm prepared by sol-gel method. DC magnetic measurement reveals a ferromagnetic transition near 150 K with low saturation magnetic moment indicates the presence of anti-site defects. The frequency depended AC susceptibility measurements and exchange bias effects conforms the competing interactions

Magnetic properties of FePt nanoparticles

Journal of Magnetism and Magnetic Materials, 2003
Abstract We have prepared FePt nanoparticles with concentrations in the vicinity of the stoichiometric Fe50Pt50 composition by means of a gas-phase-based process. The preparation technique employed allows to anneal (‘sinter’) the particles in the gas-phase prior to their deposition.

Enhancing the magnetic properties of magnetic nanoparticles

2016
Strong magnets with a high energy product are vital when optimizing the efficiency in the electric industry. But since the rare earth metals, normally used for making strong permanent magnets, are both expensive and difficult to mine, a great demand has come to cheaper types of magnets with a similar magnetic performance.

Magnetic properties of Co3O4 nanoparticles

Journal of Magnetism and Magnetic Materials, 2002
Abstract Magnetization and magnetic relaxation measurements of 200 A size Co3O4 particles are reported. Zero-field-cooled (ZFC) susceptibility exhibits a sharp peak characterizing a phase transition at Tt=∼25 K. Above Tt, the reversal magnetizations vary linearly with H and the magnetizations scale with H/(T+θ) as would occur for an antiferromagnetic

Magnetic properties of NiO nanoparticles

Physica B: Condensed Matter, 2003
Abstract NiO nanoparticles were produced by annealing Ni(OH)2 monolayer-nanoclusters above 973 K in air. Their diameters were estimated to be between 2 and 6 nm from X-ray diffraction patterns. In the magnetization measurements superparamagnetic or ferromagnetic behaviors were observed and characteristic properties of NiO ...
