Özet
The ac-susceptibility and low-field magnetisation of textured YBCO thick-film ring samples are shown to be strongly frequency dependent, measurements are interpreted in terms of an ''eddy-current'' loss model with effective time constant comparable with measurement frequencies. Numerical computation of the magnetic properties are illustrated for idealised V/I characteristics of the thick film including thermally activated flux flow.
