Hafnium, cadmium and indium impurities in 4H-SiC observed by perturbed angular correlation spectroscopy

Autor: U. Reislöhner, M. Kaltenhäuser, Wolfgang Witthuhn, M. Rüb, N. Achtziger, D. Forkel-Wirth, K. Freitag, M. Uhrmacher, J. Grillenberger, T. Licht

Publikováno v: Diamond and Related Materials. 6:1436-1439

The annealing behaviour of hafnium impurities in silicon carbide after ion implantation and the formation and stability of complexes of hafnium in 4H-SiC were studied by perturbed angular correlation spectroscopy (PAC) for the first time. Samples of

Systematic Investigation of MF3 Crystalline Compounds (M = Al, Cr, Fe, Ga, In, Sc, Ti, and V) and Fe1-xMxF3 Mixed Series (M = Ga, Cr, V)

Autor: R. Kapp, J.-M. Greneche, M. Ismaier, U. Lossen, B. Zapf, H.-R. Blank, M. Kaltenhäuser, M. Geiger, W. Kreische, M. Leblanc, M. Frank

Publikováno v: Zeitschrift für Naturforschung A. 49:361-366

The electric field gradient at the fluorine site of several crystalline trifluorides was measured by means of the time differential perturbed angular distribution method. The hyperfine data (vQ and η) are systematically analyzed by taking into accou

Dimension and entropy analysis of MEG time series from human ?-rhythm

Autor: J. Vieth, Helmut Kober, H.-R. Blank, P. Grummich, J. Heindl, R. Sporer, M. Geiger, M. Frank, W. Kreische, S. Poscher, M. Kaltenhäuser

Publikováno v: Zeitschrift f�r Physik B Condensed Matter. 91:251-256

Magnetoencephalograms (MEG) from human brain were measured by means of a 37 channel SQUID magnetometer (KRENIKON). Correlation integrals were calculated from time series exhibiting strong α-rhythm in order to give estimates of correlation dimension

Improvement of K2-entropy calculations by means of dimension scaled distances

Autor: M. Frank, H.-R. Blank, N. Müller, T. Wagner, S. Poscher, H. Köchner, J. Heindl, M. Kaltenhäuser, W. Kreische, R. Sporer

Publikováno v: Physica D: Nonlinear Phenomena. 65:359-364

The K2-entropy is evaluated for experimental time series as well as for numerically simulated ones. The conventional calculation procedure leads to results that can be extrapolated to obtain a K2-value for the time series, but in the case of experime

A Simple Model to Explain 19F-TDPAD Amplitude Characteristics

Autor: H. Köchner, M. Frank, J. Heindl, M. Kaltenhäuser, T. Wagner, S. Porscher, H.-R. Blank, N. Müller, W. Kreische

Publikováno v: Zeitschrift für Naturforschung A. 47:389-394

Since many years the 19F-TDPAD method (TDPAD = time differential perturbed angular distribution) has been used to investigate electric field gradients in fluorine compounds. In these experiments always a strong reduction of the observed interaction a
