Magnetic anisotropy of $C{o}_{x}P{t}_{1-x}$ 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 Co$\_x$Pt$\_1-x$ clusters embedded in various matrices. Using a careful analysis of magnetization curves and ZFC susceptibility measuremen…
