R. Jungblut et al., CONVERSION-ELECTRON MOSSBAUER STUDY OF THE INTERFACIAL ROUGHNESS IN MBE-GROWN NI80FE20 FE50MN50(111) BILAYERS/, Physical review. B, Condensed matter, 53(9), 1996, pp. 5488-5492
The interface roughness and variations in the magnetic moment at the i
nterface were investigated in epitaxially grown exchange biased Ni80Fe
20/Fe20Mn50 (111) bilayers by conversion-electron Mossbauer spectrosco
py. To this end, a (Fe50Mn50)-Fe-57 or (Ni80Fe20)-Fe-57 alloy probe la
yer was inserted at the interface. Using a simple model tb analyze the
data, it is shown that intermixing at the Ni80Fe20/Fe50Mn50 interface
is restricted to a zone with a thickness of only two atomic layers. T
he magnetic moments of Fe atoms in Ni80Fe20 close to this zone are not
significantly altered.
