A ferromagnetic spin structure is observed with magnetic moments oriented perpendicular to the c-axis of the hexagonal nuclear structure. The magnetic saturation moment of iron is 2.2 μB at 4.2 K from neutron diffraction and 2.0 μB from magnetic measurements and decreases in a Brillouin-like manner on heating to TC=575 K. Above 450 K an increasing but reversible disorder of the nitrogen partial structure is observed.}, language = {en} } @article{Mayer1996, author = {Mayer, Claudia}, title = {{\"A}sthetik und Macht.

Methods A double spin-echo sequence was equipped with SPSP refocusing pulses with a spectral selectivity of 1 ppm. Three-dimensional prostate ¹H-MRSI at 7T was performed with the SPSP-MRSI sequence using an 8-channel transmit array coil and an endorectal receive coil in three patients with prostate cancer and in one healthy subject. No additional water or lipid suppression pulses were used. Results Prostate ¹H-MRSI could be obtained well within specific absorption rate (SAR) limits in a clinically feasible time (10 min). Next to the common citrate signals, the prostate spectra exhibited high spermine signals concealing creatine and sometimes also choline. Residual lipid signals were observed at the edges of the prostate because of limitations in spectral and spatial selectivity. Conclusion It is possible to perform prostate ¹H-MRSI at 7T with a SPSP-MRSI sequence while using separate transmit and receive coils. This low-SAR MRSI concept provides the opportunity to increase spatial resolution of MRSI within reasonable scan times.}, language = {en} } @article{Mayer1994, author = {Mayer, Claudia}, title = {Zwischen Traum und Trauma: Einf{\"u}hrende Bemerkungen zum »Komplex Nation«}, series = {Zwischen Traum und Trauma - die Nation : transatlantische Perspektiven zur Geschichte eines Problems / Claudia Mayer-Iswandy (Hrsg.)}, journal = {Zwischen Traum und Trauma - die Nation : transatlantische Perspektiven zur Geschichte eines Problems / Claudia Mayer-Iswandy (Hrsg.)}, publisher = {Stauffenburg-Verl.}, address = {T{\"u}bingen}, isbn = {3-86057-132-X}, pages = {13 -- 24}, year = {1994}, language = {de} } @article{ZastrowRieder1980, author = {Zastrow, Udo and Rieder, G.}, title = {Zur Eingrenzung der Eigenfrequenzen eines station{\"a}r schwingenden elastischen K{\"o}rpers mittels Integralgleichungen}, series = {ZAMM - Zeitschrift f{\"u}r angewandte Mathematik und Mechanik. 60 (1980), H. 6}, journal = {ZAMM - Zeitschrift f{\"u}r angewandte Mathematik und Mechanik. 60 (1980), H. 6}, isbn = {1521-4001}, pages = {T149 -- T150}, year = {1980}, language = {de} } @article{Zastrow1978, author = {Zastrow, Udo}, title = {Zur Berechnung anisotroper Scheiben durch singul{\"a}re Integralgleichungen}, series = {ZAMM - Zeitschrift f{\"u}r Angewandte Mathematik und Mechanik.}, volume = {58}, journal = {ZAMM - Zeitschrift f{\"u}r Angewandte Mathematik und Mechanik.}, number = {6}, publisher = {Wiley-VCH}, address = {Berlin}, isbn = {1521-4001}, doi = {10.1002/zamm.19780580605}, pages = {T132 -- T133}, year = {1978}, language = {de} } @article{Mayer1997, author = {Mayer, Claudia}, title = {Zum Verh{\"a}ltnis von Macht und Gewalt im Geschlechterkampf.
