Abstract

The influence of partial substitution of Ca by La on (Bi,Pb)2223 phase purity and intergranular dissipative processes is characterized by XRD and a.c.magnetic susceptibility function of temperature and a.c. field amplitude. The intergranular phase diagram Hp function of temperature and the intragrain contributions of effective volume fraction of the grains fg were estimed..
