Abstract. Local crystalline structure of hypo-and hyperstoichiometric SmCox alloys with x = 5.15, 4.95, 4.0, 3.75 heat treated in different conditions was investigated by means of the X-ray absorption spectroscopy. Experimental spectra were measured above the L3-Sm absorption edge. EXAFS-analysis shows that stacking faults appear in hyperstoichiometric alloys SmCo4 and SmCo3.75, confirming the hypothesis of "high coercive state, induced by phase transformations, changing the state of the grain surface in basic phase". L3-Sm XANES spectra demonstrate the reduction of the "white line" amplitude in Sm-enriched samples.
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.
