A positive sign of D demonstrates that the spin-orbit contribution to the zero-field splitting exceeds by far that of the spin-spin interaction. A principal axis of the fine structure tilted by 59° against the crystal c-axis as well as the exceptionally high zero-field splitting D can be qualitatively understood by the occurrence of additional close-lying defect levels in defect clusters resulting in comparatively large second-order spin-orbit coup¬ling. A tentative assignment to vacancy clusters is supported by the observed annealing behavior. }}, author = {{Scholle, Andreas and Greulich-Weber, Siegmund and Rauls, Eva and Schmidt, Wolf Gero and Gerstmann, Uwe}}, issn = {{1662-9752}}, journal = {{Materials Science Forum}}, pages = {{403--406}}, title = {{{Fine Structure of Triplet Centers in Room Temperature Irradiated 6H-SiC}}}, doi = {{10.4028/www.scientific.net/msf.645-648.403}}, volume = {{645-648}}, year = {{2010}}, } @article{15846, author = {{Schumacher, Stefan and Galbraith, Ian and Ruseckas, Arvydas and Turnbull, Graham A. and Samuel, Ifor D.

The central quantity is the transverse spin susceptibility, from which the complete excitation spectrum, including single-particle spin-flip Stoner excitations and collective spin-wave modes, can be obtained. The susceptibility is derived from many-body perturbation theory and includes dynamic correlation through a summation over ladder diagrams that describe the coupling of electrons and holes with opposite spins. In contrast to earlier studies, we do not use a model potential with adjustable parameters for the electron-hole interaction but employ the random-phase approximation. To reduce the numerical cost for the calculation of the four-point scattering matrix we perform a projection onto maximally localized Wannier functions, which allows us to truncate the matrix efficiently by exploiting the short spatial range of electronic correlation in the partially filled d or f orbitals. Our implementation is based on the full-potential linearized augmented-plane-wave method. Starting from a ground-state calculation within the local-spin-density approximation (LSDA), we first analyze the matrix elements of the screened Coulomb potential in the Wannier basis for the 3d transition-metal series. In particular, we discuss the differences between a constrained nonmagnetic and a proper spin-polarized treatment for the ferromagnets Fe, Co, and Ni. The spectrum of single-particle and collective spin excitations in fcc Ni is then studied in detail. The calculated spin-wave dispersion is in good overall agreement with experimental data and contains both an acoustic and an optical branch for intermediate wave vectors along the [100] direction. In addition, we find evidence for a similar double-peak structure in the spectral function along the [111] direction. To investigate the influence of static correlation we finally consider LSDA+U as an alternative starting point and show that, together with an improved description of the Fermi surface, it yields a more accurate quantitative value for the spin-wave stiffness constant, which is overestimated in the LSDA.}}, author = {{Şaşıoğlu, Ersoy and Schindlmayr, Arno and Friedrich, Christoph and Freimuth, Frank and Blügel, Stefan}}, issn = {{1550-235X}}, journal = {{Physical Review B}}, number = {{5}}, publisher = {{American Physical Society}}, title = {{{Wannier-function approach to spin excitations in solids}}}, doi = {{10.1103/PhysRevB.81.054434}}, volume = {{81}}, year = {{2010}}, } @article{4123, abstract = {{GaAs-based semiconductor microdisks with high quality whispering gallery modes (Q44000) have been fabricated.A layer of self-organized InAs quantumdots (QDs) served as a light source to feed the optical modes at room temperature.

In addition, a validation study applying 24 h dietary recalls was performed.DesignUsing the variance-based Max_r method, a list of eighty-two foods was compiled from data obtained by 3 d weighed dietary records. The foods were used to design an FFQ, the comprehensibility of which was evaluated in a feasibility study. In addition, the FFQ was validated in a subset of 101 children from the German Infant Nutritional Intervention Study (GINI PLUS) against one 24 h dietary recall.ResultsThe feasibility study attested a good acceptance of the FFQ. Mean intake of foods compared well between the FFQ and the 24 h dietary recall, although intake data generated from the FFQ tended to be higher. This difference became less apparent at the nutrient level, although the estimated average consumption of arachidonic acid and EPA using the FFQ still exceeded values recorded with the 24 h recall method by 45 % and 29 %, respectively.ConclusionsOn the basis of the systematic selection process of the food list, the established practicability of the FFQ and the overall plausibility of the results, the use of this FFQ is justified in future epidemiological studies.}}, author = {{Stiegler, Petra and Sausenthaler, Stefanie and Buyken, Anette and Rzehak, Peter and Czech, Daniel and Linseisen, Jakob and Kroke, Anja and Gedrich, Kurt and Robertson, Claire and Heinrich, Joachim}}, issn = {{1368-9800}}, journal = {{Public Health Nutrition}}, pages = {{38--46}}, title = {{{A new FFQ designed to measure the intake of fatty acids and antioxidants in children}}}, doi = {{10.1017/s1368980009005813}}, year = {{2009}}, } @book{2792, editor = {{Kundisch, Dennis and Veit, D. and Weitzel, T. and Weinhardt, C.}}, publisher = {{Springer}}, title = {{{Proceedings of the 4th International Workshop on Enterprise Applications and Services in the Finance Industry}}}, volume = {{23}}, year = {{2009}}, } @misc{27938, author = {{Dell'Aere, A. and Hirsch, M. and Klöpper, B. and Koester, M. and Krüger, M. and Krupp, A. and Müller, T. and Oberthür, S. and Pook, S. and Priesterjahn, C. and Romaus, C. and Schmidt, A. and Sondermann-Wölke, C. and Tichy, M. and Vöcking, H. and Zimmer, D.}}, isbn = {{978-3-939350-54-5}}, publisher = {{Verlagsschriftenreihe des Heinz Nixdorf Instituts, Paderborn}}, title = {{{Verlässlichkeit selbstoptimierender Systeme - Potenziale nutzen und Risiken vermeiden}}}, volume = {{235}}, year = {{2009}}, } @inbook{17316, author = {{Brennecke, Andreas and Finke, Stefan and Oevel, Gudrun and Roth, A.}}, booktitle = {{Hochschulentwicklung innovativ gestalten – Das Projekt Locomotion an der Universität Paderborn}}, editor = {{Hauenschild, W. and Meister, D.
