MAGNETIC SMALL-ANGLE X-RAY-SCATTERING

We present first experimental results of the extension of X-ray Magnet ic Circular Dichroism (X-MCD) to Small Angle X-ray Scattering (SAXS). The purpose of this study is to determine size distributions and corre lations lengths in the nanometer range of magnetic precipitates in gra nular systems. Magnetic scattering curves obtained with a GdFe system at the GdL3 edge are compared with reference measurements taken with A nomalous Small Angle X-ray Scattering (ASAXS) at the Fe K-edge. The pr ofile of the scattering curves indicate a correlation maximum. The mag netic scattering intensity can be explained within the frame of X-MCD results and magnetic contributions to the anomalous scattering factors f' and f ''.
