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 ...

Magnetism in nanoparticles: tuning properties with coatings

Journal of Physics: Condensed Matter, 2013
This paper reviews the effect of organic and inorganic coatings on magnetic nanoparticles. The ferromagnetic-like behaviour observed in nanoparticles constituted by materials which are non-magnetic in bulk is analysed for two cases: (a) Pd and Pt nanoparticles, formed by substances close to the onset of ferromagnetism, and (b) Au and ZnO nanoparticles,

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 ...
