Abstract
Crystalline and magnetic structure as well as the interlayer exchange coupl ing in MBE grown Fe/FeSi multilayers are investigated. From conversion elec tron Mossbauer spectroscopy and ion beam channeling measurements the spacer FeSi material is found to be stabilized in a crystalline metastable metall ic FeSi phase with the CsCl structure. Strong non-oscillatory interlayer ex change coupling is identified with magnetometry and synchrotron Mossbauer r eflectometry. From the fits of the time spectrum and the resonant theta-2 t heta scans a model for the sublayer magnetization of the multilayer is dedu ced.
