Electronic properties of DyCo3B2 compound

The electronic structure of DyCo3B2 compound has been studied by X-ray phot oemission spectroscopy (XPS) and the ab initio self-consistent tight bindin g linear muffin tin orbital (TB LMTO) method. We have found a good agreemen t between the experimental XPS valence band spectrum and theoretical LMTO c alculations. Results showed that the DyCo3B2 compound is magnetically order ed with a small magnetic moment on the cobalt atom, which is antiparallel t o the dysprosium moment. The values of the magnetic moments on Co atoms str ongly depend on the local environment. We have also compared the electronic structure and magnetic properties of DyCo3B2 compound with those of the Dy Co5 compound. (C) 1999 Elsevier Science B.V. All rights reserved.
