Abstract

The magnetic J_cs are higher than 10000 A/cm² at 1T and 77K, even though the whole volume of sample was used to calculate the magnetic J_c for high J_cYBCO superconductors prepared with the powder melting process (PMP). It is found that the transport J_cs were usually higher than magnetic J_cs, J_c alpha B ^-12/, and the reduced F_p met with the function of b ^.85(1-b)² at 85K. The strong flux pinning effects were related to the dense defects such as dislocations and dislocation dipoles around the 211 particles.
