Abstract

Magnetic dead layers near the Fe/Ru interface in iron films grown on Ru(0001) and in Fe/Ru multilayers have been reported previously. In this paper the CEMS analysis is applied to explain why these interfacial Fe atoms are nonmagnetic. The CEMS spectra of the uncoated bcc-Fe surface clearly show the ferromagnetic order. After covering with ruthenium, the characteristic changes in the conversion electron Mössbauer spectrum were observed, which indicate existence of a nonferromagnetic phase near the Fe/Ru interface. The measured value of the isomer shift of the interface component suggests that the bcc phase persists after covering of the Fe film with Ru.
