Resonant photoemission with circular polarized light on magnetized LSMO

Autor: Richter, M. C., Heckmann, O., Mun, B. S., Fadley, C. S., Mercey, B., Hricovini, K.

We have used resonant photoemission with circular polarized light as a new tool to obtain information about the electronic structure of half-metals. After careful sample surface preparation of La0.7Sr0.3MnO3, we have obtained a dichroic signal for th

Observation and resonant x-ray optical interpretation of multi-atom resonant photoemission effects in O 1s emission from NiO

Autor: Mannella, N., Yang, S. -H., Mun, B. S., de Abajo, F. J. Garcia, Kay, A. W., Sell, B. C., Watanabe, M., Ohldag, H., Arenholz, E., Young, A. T., Hussain, Z., Van Hove, M. A., Fadley, C. S.

Publikováno v: Phys. Rev. B 74, 165106 (2006)

We present experimental and theoretical results for the variation of the O 1s intensity from a NiO(001) surface as the excitation energy is varied through the Ni 2p1/2,3/2 absorption resonances, and as the incidence angle of the radiation is varied f

Synthesis and characterization of atomically-thin graphite films on a silicon carbide substrate

Autor: Rollings, E., Gweon, G. -H., Zhou, S. Y., Mun, B. S., McChesney, J. L., Hussain, B. S., Fedorov, A. V., First, P. N., de Heer, W. A., Lanzara, A.

This paper reports the synthesis and detailed characterization of graphite thin films produced by thermal decomposition of the (0001) face of a 6H-SiC wafer, demonstrating the successful growth of single crystalline films down to approximately one gr

Correction of non-linearity effects in detectors for electron spectroscopy

Autor: Mannella, N., Marchesini, S., Kay, A. W., Nambu, A., Gresch, T., Yang, S. -H., Mun, B. S., Bussat, J. M., Rosenhahn, A., Fadley, C. S.

Publikováno v: Journal of Electron Spectroscopy and Related Phenomena 141, 45 (2004)

Using photoemission intensities and a detection system employed by many groups in the electron spectroscopy community as an example, we have quantitatively characterized and corrected detector non-linearity effects over the full dynamic range of the

Direct Observation of High-Temperature Polaronic Behavior In Colossal Magnetoresistive Manganites

Autor: Mannella, N., Rosenhahn, A., Booth, C. H., Marchesini, S., Mun, B. S., Yang, S. -H., Ibrahim, K., Tomioka, Y., Fadley, C. S.

Publikováno v: Phys. Rev. Lett. 92, 166401 (2004)

The temperature dependence of the electronic and atomic structure of the colossal magnetoresistive oxides $La_{1-x}Sr_{x}MnO_{3}$ (x = 0.3, 0.4) has been studied using core and valence level photoemission, x-ray absorption and emission, and extended
