摘要：

Complex a.c. susceptibility measurements in a broad field range (1 Oe < h(ac) < 100 Oe) have been made on Bi-Pb-Sr-Ca-Cu-O (Bi-2223 phase) bulk samples obtained by combined magnetic melt texturing and hot pressing. Highly anisotropic properties are observed. Improved intergranular coupling is obtained in the direction perpendicular to the applied stress and the magnetic field direction. An intragranular peak is also observed for the same direction. This is the first time that an intragranular loss peak has been clearly seen in a bismuth-based compound, which indicates that the intragranular contribution is strongly increased.
