Photoemission studies of Pt3MnxCr1-x

The polycrystalline Pt3Cr1-xMnx (x=0,..., 1) materials are a model system f or the investigation of magnetic ordering and verification of band calculat ion schemes. Five samples with stoichiometries x=0, 0.31 0.5, 0.7 and 1 wer e produced and analysed using X-ray diffraction and SEM. Subsequently, phot oemission measurements were carried out at the synchrotron radiation source at Daresbury. The photoemission measurements indicated that there is littl e hybridisation between the Mn and Cr 3d states. (C) 1999 Elsevier Science B.V. All rights reserved.
