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 Cr2O3 Nanoparticles

Journal of Magnetism and Magnetic Materials, 2004
Abstract Magnetization measurements of ∼150 A size Cr 2 O 3 particles prepared by chemical precipitation are reported. Zero-field-cooled (ZFC) susceptibility exhibits a peak characterizing a blocking behaviour at T B ≈40 K. Above the bifurcation point of ∼160 K the reversal magnetizations vary linearly with H , whereas below it both ZFC and field-

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 ...
