Chemical order and size effects on the magnetic anisotropy of FePt and CoPt nanoparticles
Stanislas Rohart, Florent Tournus, Véronique Dupuis
We investigate the consequence of the dimension reduction on the magnetic anisotropy of FePt and CoPt nanoparticles. Using an extension of the magnetic anisotropy model of Néel, we…
Structural and magnetic properties of CoPt mixed clusters
Luc Favre, Véronique Dupuis, Estela Bernstein +7
In this present work, we report a structural and magnetic study of mixed Co58Pt42 clusters. MgO, Nb and Si matrix can be used to embed clusters, avoiding any magnetic interactions…
Magnetic anisotropy of clusters embedded in matrix: Influences of the cluster chemical composition and the matrix nature
Stanislas Rohart, Cécile Raufast, Luc Favre +3
We report on the magnetic properties of CoPt clusters embedded in various matrices. Using a careful analysis of magnetization curves and ZFC susceptibility measuremen…
Micro-SQUID technique for studying the temperature dependence of switching fields of single nanoparticles
C. Thirion, W. Wernsdorfer, M. Jamet +4
An improved micro-SQUID technique is presented allowing us to measure the temperature dependence of the magnetisation switching fields of single nanoparticles well above the critic…
Interface magnetic anisotropy in cobalt clusters embedded in a platinum or niobium matrix
M. Jamet, M. Negrier, V. Dupuis +7
A low concentration of cobalt clusters with a fcc structure and containing almost one thousand atoms are embedded in two different metallic matrices: platinum and niobium. Samples…
Magnetic Anisotropy of a Single Cobalt Nanoparticle
M. Jamet, W. Wernsdorfer, C. Thirion +4
Using a new microSQUID set-up, we investigate magnetic anisotropy in a single 1000-atoms cobalt cluster. This system opens new fields in the characterization and the understanding…
