摘要：

Macroscopic critical current densities jcm of the (Bi0.9Pb0.1)2-Sr2Ca2Cu3O10+x polycrystalline strongly oriented sample have been measured by two inductive methods - AC susceptibility measurements and magnetic flux profile measurements - up to superimposed DC magnetic field of 140 mT. It is shown that the sample exhibits high jcm(77 K) of 870 A/cm2 and 200 A/cm2 at magnetic field of zero and 50 mT, respectively. © 1990.
