Ag-Ge-Se system is an easy glass former in a wide composition range not far from the Se corner of the equilibrium phase diagram. The existence of a liquid miscibility gap impacts on the glass morphology where Ag-rich zones alternate with Ag depleted ones which size depends on composition. In order to analyze the short range order, 0.5 at.% Fe was added as a probe in the synthesis stage. Mössbauer spectra of these glasses were obtained at room and lower temperatures. Two types of environments were observed. The corresponding Debye temperatures, and the fraction of Fe atoms in each environment were determined. Additionally, magnetic moment was measured as a function of temperature and applied magnetic field. From m(H) and m(T) curves it is evident that the magnetization of the glasses has two components, i.e., a blocked one even up to room temperature that saturates at low field, and a paramagnetic one which does not saturate even at the largest applied field. The Mössbauer spectroscopy results are discussed and correlated to the morphology and magnetic behavior of these glasses.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
