الوصف: | We present the temperature dependence of alpha-relaxation times of 13 glass formers determined from broadband dielectric spectroscopy, also including data from aging measurements. The data sets partly cover relaxation-time ranges of up to 16 decades enabling a critical test of the validity of model predictions. For this purpose, the data are provided for electronic download. Here we employ these results to test the applicability of the Vogel-Fulcher-Tammann equation and a recently proposed new approach that was demonstrated to provide superior fits of a vast collection of viscosity data. Comment: 6 pages, 5 figures, final version with minor revisions according to referee demands. The relaxation time data published in the present work can be downloaded at http://link.aps.org/supplemental/10.1103/PhysRevE.81.051504 |
