The field and temperature dependencies of the intra-grain and inter-grain critical current densities in (Tl0.5Pb0.5)(Sr0.8Ba0.2)(2)Ca2Cu3Ox ceramics

The field and temperature dependencies of the intra-grain and inter-grain critical current densities in (Tl0.5Pb0.5)(Sr0.8Ba0.2)(2)Ca2Cu3Ox ceramics

We report investigations of the magnetization and the associated critical current density of a Tl0.5Pb0.5)(Sr0.8Ba0.2)(2)Ca2Cu3Ox ceramic sample in T and H varying from 10(-2) to 7x10(4) Oe and 4.2 K to T-c approximate to 110 K. At high enough temperature, the M vs H relationship exhibits 5 differen...
