Fe/ X ( X = Au, Ag, Cu) epitaxial multilayer films were prepared on MgO(001) substrates at a substrate temperature of 300 °C by alternate deposition of Fe and X atomic layers. The composition of Fe/ X multilayer was varied from the ratio around the L 1 0 phase stoichiometry (Fe: X = 50:50) to X ‐rich region. The effects of X atom on the microstructure, magnetic properties, and formation of L 1 0 ordered phase were investigated. X‐ray analysis has shown that L 1 0 ordered phase is formed in the Fe/Au system and that a stronger intensity of L 1 0 phase is observed in an Au‐rich compositional region. No evidence of L 1 0 ordered phase formation is recognized for the Fe/Ag and the Fe/Cu systems. (© 2007 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
