Microscopic studies of metallic multilayers using Mössbauer probes

Recent topics in multilayer studies are the giant magnetoresistance phenomena and interlayer exchange couplings between magnetic layers through non-magnetic intervening layers. Several measurements have been carried out concerning these problems, utilizing¹⁹⁷Au,¹¹⁹Sn and⁵⁷Fe as Mössbauer probes. In this article, experimental results are described and the use of Mössbauer spectroscopy for these problems is discussed.
