Ageing dynamics of ferromagnetic and re-entrant spin glass phases in a stage-2 Cu(0.80)Co(0.20)Cl(2) graphite intercalation compound.

Ageing dynamics of a re-entrant ferromagnet stage-2 Cu(0.8)Co(0.2)Cl(2) graphite intercalation compound has been studied using DC magnetization measurements.

Monodispersed core-shell Fe3O4@Au nanoparticles.

The ability to synthesize and assemble monodispersed core-shell nanoparticles is important for exploring the unique properties of nanoscale core, shell, or their combinations in technological applications. This paper describes findings of an investigation of the synthesis and assembly of core (Fe(3)O(4))-shell (Au) nanoparticles with high monodispersity. Fe(3)O(4) nanoparticles of selected sizes were used as seeding materials for the reduction of gold precursors to produce gold-coated Fe(3)O(4) nanoparticles (Fe(3)O(4)@Au).
