In this paper, we present some specific chemical and magnetic order results obtained on bimetallic FeRh nanoparticles prepared under non-equilibrium conditions using mass-selected Low Energy Cluster Beam Deposition. Clusters around 7 nm incident diameter are in situ sandwiched between amorphous carbon films before transfer air, with different surface coverage (from nearly isolated particles to ...

Due to their ability reversibly absorb/desorb hydrogen without hysteresis, Pd--Au nanoalloys have been proposed as materials for sensing. For sensing, it is important that absorption/desorption isotherms are reproducible and stable over time. A few studies pointed the influence of short long range chemical order on these isotherms, but many aspects impact remained unexplored. Here, we use alloy...

The focus of this review is on the physical and magnetic properties that are related to efficiency monometallic nanoparticles used in biomedical applications, such as resonance imaging (MRI) or nanoparticle hyperthermia, how model these by theoretical methods, where discussion based example cobalt nanoparticles. Different simulation systems (cluster, extended slab, models) critically appraised ...
