Abstract
Local crystalline structure of hypo- and hyperstoichiometric SmCo x 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. © 2009 IOP Publishing Ltd.
