Reversed size-dependent stabilization of ordered nanophases

Increasing nanoparticle size usually increases the stability of ordered phases within them. In contrast, the authors show here that the L11 ordered phase only forms in AgPt nanoparticles smaller than 2.5 nm because the segregation of a monolayer Ag shell constrains the nanophase which becomes unstab...
