Effect of partial substitution of Ca by La on intergranular processes in (Bi,Pb):2223 superconductors

Domenii publicaţii > Fizica + Tipuri publicaţii > Articol în revistã ştiinţificã

Autori: A. V. Pop, I. Matei, M. Pop

Editorial: Journal of Optoelectronics and Advanced Materials , 9, p.2451 ̵, 2007.

Rezumat:

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.
