Size-Dependent Chemical and Magnetic Ordering in L10-FePt Nanoparticles

Direct evidence for size‐dependent chemical and magnetic ordering in L10‐FePt nanoparticles is obtained by measuring monodisperse nanoparticles prepared by the “salt‐matrix annealing” technique. Quantitative correlations show that the long‐range chemical‐ordering parameter, Curie temperature (see fi...

Zusammenfassung:Direct evidence for size‐dependent chemical and magnetic ordering in L10‐FePt nanoparticles is obtained by measuring monodisperse nanoparticles prepared by the “salt‐matrix annealing” technique. Quantitative correlations show that the long‐range chemical‐ordering parameter, Curie temperature (see figure), and saturated magnetization drop significantly with decreasing particle size.
