The moir\'e pattern created by the epitaxy of a graphene sheet on an iridium substrate can be used as a template for the growth of 2D atomic or cluster arrays. We observed for the first time a coherent organization of hard magnetic preformed FePt nan

The FePt alloy, when chemically ordered in the $\mathrm {L}1 _{0}$ phase, is among the magnetic materials displaying the highest magnetic anisotropy constant (K around $7 \mathrm{MJ}/ \mathrm {m}^{3})$. Therefore it is a perfect candidate for ultra-h

In this work, we have focused on the elaboration and characterization of nanostructured L10-CoPt magnetic dot arrays prepared by depositing Co50Pt50 nanoparticles preformed in the gas phase on Si substrates patterned by electron beam lithography (EBL

An original physical route is proposed to organize size-selected bimetallic nanoparticles on graphite surfaces. This approach is based on the soft landing of preformed clusters and is demonstrated for bimetallic Au x Pt 1 − x clusters of different

Self organisation of Pt and Au clusters deposited on graphite: the role of reactivity

Autor: Patrice Mélinon, L. Bardotti, Florent Tournus, Michel Pellarin, Michel Broyer

Publikováno v: The European Physical Journal D. 63:221-224

Spontaneous organisation of preformed size selected platinum and gold clusters on graphite is discussed in terms of reactivity with residual gases. The difference in reactivity between gold and platinum can explain the spontaneous organisation in an
