Critical current in Tl/sub 2/Ba/sub 2/Ca/sub 2/Cu/sub 3/O/sub y/ superconductor

Journal Article · · Mod. Phys. Letters B; (United States)
Magnetic critical current J/sub c/ of Tl/sub 2/Ba/sub 2/Ca/sub 2/Cu/sub 3/O/sub y/ was measured. It is comparable with that of YBa/sub 2/Cu/sub 3/O/sub 7-x/ in a field H up to 60 kOe at T /le/ 15 K. For higher temperature, the J/sub c/ of Tl/sub 2/Ba/sub 2/Ca/sub 2/Cu/sub 3/O/sub y/ decreases more rapidly than that of YBa/sub 2/Cu/sub 3/O/sub 7-x/. Possible origin is discussed.
