      abstract     = {This work presents the correlation between the morphology
                      and magnetic properties of (Fe/Si)3 multilayers with
                      different Fe layer thicknesses and fixed Si spacer thickness
                      in a broad temperature range (View the MathML
                      source5<T<800K). Films were prepared by thermal evaporation
                      under ultrahigh vacuum onto a buffer layer of Fe/Ag
                      deposited on a GaAs(001) substrate. Transmission electron
                      microscopy reveals good epitaxial growth and phase
                      transformations in the c-FeSi phase formed during deposition
                      as well as upon subsequent annealing of the sample up to 800
                      K. Remanence to saturation magnetization MR/MS ratios and
                      saturation fields are related to several types of interlayer
                      exchange coupling. 90°-coupling and a superposition of 90°
                      and antiferromagnetic interlayer exchange coupling are found
                      depending on the Fe layer thickness. Magnetization curves
                      were investigated as a function of temperature by in situ
                      annealing. They show an irreversible thermal process as
                      temperature increases from 300 to 450 K that is correlated
                      to the formation of a ferromagnetic silicide phase. At
                      higher temperature this phase transforms into a paramagnetic
                      Fe–Si phase.},
