FeCo–Au core-shell nanocrystals

Abstract

A one-step synthesis of heterostructured high magnetic moment FeCo–Au nanocrystals was demonstrated. The nanocrystals possess a cubic shape and have an average size of 30nm. Compositional analysis revealed the detailed distribution of each element within the nanocrystal. The crystalline structure of the components and their epitaxial relationship were determined by structural analysis. The heterostructured FeCo–Au nanocrystals are promising in biomedical applications as well as in fundamental studies of interactions in the nanoscale.
