New insights into structural and magnetic properties of Ce doped ZnO nanoparticles

Journal of Alloys and Compounds, 2018
Cerium doped ZnO nanoparticles were successfully prepared by the co-precipitation method using cerium sulphate as dopant precursor. The effect of cerium doping on the structural, morphological and optical properties of the obtained nanoparticles were ...

Magnetic properties in CeCo2 nanoparticles

Journal of Magnetism and Magnetic Materials, 2002
Abstract Bulk CeCo 2 is characterized as a Pauli paramagnet, both Ce and Co are essentially nonmagnetic. The data of χ ( T ) show that CeCo 2 nanoparticles exhibit extremely complex magnetic properties. Two magnetic phases, a major paramagnetic component and a minor ferromagnetic component, were detected in CeCo 2 nanoparticles.

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 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

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
