Popis: | We have investigated the temperature effect on Mn dilution into InSb substrates by means of high-resolution core level spectroscopy, surface EXAFS, and by X-ray Magnetic Circular Dichroism (XMCD) using synchrotron radiation. Samples were prepared by manganese deposition of 1, 2, 4 and 8 ML at room temperature (RT) and at 500K on InSb(001) (4 x 2)c(8 x 2) surfaces. By fitting In 4d and Sb 4d core level spectra with Voigt-functions, we identify metallic In and Sb atoms segregated on the surface. EXAFS results show MnSb-like compound formation with hexagonal structure in which Mn atoms replace some antimony atoms in the first nearest neighbours shell. |
