Mc. Frischherz et al., COMPARATIVE-STUDY OF EXPERIMENTAL-TECHNIQUES FOR IRREVERSIBILITY LINES AND CRITICAL-CURRENT DENSITIES IN HIGH-TEMPERATURE SUPERCONDUCTORS, Superconductor science and technology, 8(7), 1995, pp. 485-496
We review the literature on different experimental techniques used to
determine the irreversibility line and the critical current density in
high-temperature superconductors. Some of our own recent results pert
inent to this subject are presented. In particular, SQUID and a.c. sus
ceptibility measurements performed on a large single crystal and a mel
t-processed sample are compared.
