Magnetic Properties of Lanthanide Chalcogenide Semiconducting Nanoparticles

Journal of the American Chemical Society, 2006
To understand the importance of the band gap to the magnetic ordering in magnetic semiconductors, we have studied the effect of particle size on the ferromagnetic Curie temperature in semiconducting EuS. We have synthesized capped approximately 20 nm EuS nanoparticles using a single-source precursor, [Eu(S(2)CN(i)()Bu(2))(3)Phen] decomposed in ...

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 ...

Chemical and magnetic properties characterization of magnetic nanoparticles

2015 IEEE International Instrumentation and Measurement Technology Conference (I2MTC) Proceedings, 2015
This paper deals with the characterization of magnetic iron oxide nanoparticles. Pure magnetite (Fe 3 O 4 ) and noble metal doped magnetite were synthesized following a new sustainable microwave-assisted method. Furthermore, an experimental analysis was carried out to investigate the chemical and magnetic properties of these new nanopowders ...

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 magnetically isolated L1-FePt nanoparticles

Applied Physics Letters, 2004
This letter reports the results obtained by measuring the temperature dependence of the coercivity of magnetically isolated L10-FePt nanoparticles in agglomeration-free films deposited by using a dispersion stabilizer and a spin-coat technique. These measurements not only give the basic magnetic parameters of the nanoparticles but also provide ...

Structural and magnetic properties of ?-Fe2O3 nanoparticles

Applied Organometallic Chemistry, 1998
The magnetic properties of alpha-Fe2O3 nanoparticles of different shapes (spherical, rhombohedral and acicular), prepared as powders by a chemical route, have been investigated. The particle size effect on the Morin transition (T-M = 263 K in the bulk system) have been studied by analyzing the temperature dependence of the zero-field-cooled (ZFC) and ...

Magnetic properties of Aucore-Coshell nanoparticles

Journal of Applied Physics, 2011
Aucore-Coshell nanoparticles were synthesized by a wet-chemical method, and their magnetic properties were characterized. By comparing the blocking temperature of Aucore-Coshell nanoparticles to pure cobalt nanoparticles of the same size, it is proposed that cobalt spins in the shell are all aligned by exchange interaction to form single domain nano ...

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.
