Anisotropic Superparamagnetism of Monodispersive Cobalt-Platinum Nanocrystals
F. Wiekhorst, E. Shevchenko, H. Weller +1
Based on the high-temperature organometallic route (Sun et al. Science 287, 1989 (2000)), we have synthesized powders containing CoPt_3 single crystals with mean diameters of 3.3(2…
Damping of spin waves and singularity of the longitudinal modes in the dipolar critical regime of the Heisenberg-ferromagnet EuS
P. Boeni, B. Roessli, D. Goerlitz +1
By inelastic scattering of polarized neutrons near the (200)-Bragg reflection, the susceptibilities and linewidths of the spin waves and the longitudinal spin fluctuations were det…
Nucleation of Stable Superconductivity in YBCO-Films
J. Koetzler
By means of the linear dynamic conductivity, inductively measured on epitaxial films between 30mHz and 30 MHz, the transition line to generic superconductivity is studied…
Two-Dimensional Fluctuations Close to the Zero-Field Transition of Bi_2Sr_2CaCu_2O_8
J. Kötzler, M. Kaufmann
The ac-conductivity along the CuO-layers of epitaxial films and single crystals of thicknesses 0.2mm reveals clear signatures for 2D-ordering. In particul…
Universality of Frequency and Field Scaling of the Conductivity Measured by Ac-Susceptibility of a Ybco-Film
J. Kötzler, G. Nakielski, M. Baumann +3
Utilizing a novel and exact inversion scheme, we determine the complex linear conductivity from the linear magnetic ac-susceptibility which has been measured from 3\,mHz to…
