Abstract
Nanocrystalline materials have been proposed to present a new solid-state structurewhich exhibits neither long-range order (like crystals) nor short-range order (like glasses).They consistof two components with comparable volume fractions:a crystalline component and an interfacialcomponent.M(?)ssbauer spectroscopy has been used to investigate the atomic structure,the distributionof hyperfine field,superparamagnetism and interactions between interface and nanocrystal cores.
