SOFT-X-RAY EMISSION-SPECTROSCOPY OF NIAS-TYPE MNTE AT THE MN 2P CORE THRESHOLD

Resonant soft X-ray emission spectra of NiAs-type MnTe have been measu red near the Mn 2p threshold using synchrotron radiation. The spectra consist of two structures due to elastic and inelastic scatterings and their relative intensity depends strongly on the excitation photon en ergy. The inelastic scattering peak around 3-4 eV below the elastic sc attering peak can be attributed to d-d excitation. In order to interp ret the resonant behaviour, we have calculated the soft X-ray emission spectra of NiAs-type MnTe on the basis of a cluster model including e lectron-electron interactions and p-d hybridization. The theoretical r esults reproduce the basic structures of the experimental spectra, tho ugh we notice a difference in their relative intensities. (C) 1998 Els evier Science B.V.
