Mössbauer and magnetic study of interface structure of Fe/SixFe1−x multilayers with antiferromagnetic interlayer coupling

The structural and magnetic properties of Fe/SixFe1−x multilayers (Mls) have been studied by the conversion electron Mössbauer spectroscopy (CEMS) and magnetic measurements. We believe that the Fe-Si silicides responsible for the AF coupling in Fe/Si multilayers are semiconducting SixFe1−x phases ri...

Zusammenfassung:	The structural and magnetic properties of Fe/SixFe1−x multilayers (Mls) have been studied by the conversion electron Mössbauer spectroscopy (CEMS) and magnetic measurements. We believe that the Fe-Si silicides responsible for the AF coupling in Fe/Si multilayers are semiconducting SixFe1−x phases rich in Si which appear in inhomogeneous spacer layer. Antiferromagnetically coupled Fe/Si multilayers have been successfully applied as artificial antiferromagnets in the magnetoresistive (Fe/Si)15/Fe/Co1/Cu/Co2 pseudo-spin-valve system.
