Investigation of magnetic coupling phenomena in Fe1-xCrx/Cr-superlattices with spin-polarized neutrons

We present the results of temperature dependent measurements of magneticall y coupled Fe1-xCrx/Cr-superlattices. These results are supplementary to the ones known for non-collinearly coupled Fe/Cr-superlattices. By systematica lly varying the Cr concentration x we cover a wide range of the Fe1-xCrx-ph ase diagram. As an experimental technique spin-polarized neutron reflectivi ty with spin analysis and high-angle neutron scattering proves to be ideal for this work. (C) 1999 Published by Elsevier Science B.V.
