In this work we report on the enhancement of the ferromagnetism of amine/organic acid capped Au nanoparticles (AuNPs) by incorporation of yttrium-oxide (Y2O3). The magnetization measurements displayed a ferromagnetic (FM) loop with a coercive field [...]

Ferromagnetic Resonance in amine/organic acid caped Au-nanoparticles assisted by rare-earths oxides

Iwamoto W., Lesseux G.G., Rettori C., Rettori D., Rosas V.H., Vautier-Giongo C., Universidade Estadual de campinas, BR

Amine/organic acid caped Au-nanoparticles (Au-NPs) were prepared by reducing gold tetrachloroaurate (HAuCl4.3H2O) and rare-earth (RE)-oxides (RE = Er and Y and monodisperse samples of caped Au-NPs of ~10 nm in diameter were obtained. The magnetization [...]
