Abstract
[fcc-Fe/Cu] multilayers on Cu(001) were investigated by fluorescence E XAFS (extended X-ray absorption fine structure) in order to study rela tionship between local structures around the Fe atoms and their magnet ic properties. The EXAFS analysis revealed that the Fe-Fe bond length of fcc-Fe becomes longer with the increase of the surface roughness of the Cu substrate, thus resulting in increase of the magnetic moment p er Fe atom in fcc-Fe. The magnetic moments per Fe atom which were esti mated from the volume ratio obtained by EXAFS results agreed with thos e measured by VSM. (C) 1998 Elsevier Science B.V. All rights reserved.
