We have performed measurements of temperature dependent electrical resistivity ρ ( T ) under pressures up to 27 kbar and down to 0.1 K on single crystals of the Ce3Ir4Sn13 heavy fermion compound. At ambient pressure (P=0) we have identified in the �

The Bi2Sr2Ca2Cu3 O10+x (Bi-2223) is one of the main high temperature superconductors for applications. One of these applications is the Superconductor Fault Current Limiter (SCFCL), which is a very promising high temperature superconducting device. S

Investigation of Pb-free Bi-2223 high temperature sintering

Autor: H.A. Borges, E. Hering, J.H.G. Lima, A. Polasek, Luiz Antonio Saléh, E.T. Serra, G.S. de Oliveira, F. Rizzo

Publikováno v: IEEE Transactions on Applied Superconductivity. 15:3141-3144

The Bi-2223 performance could be significantly improved by melt processing. However, it is a very difficult task, partly due to the volatility of Pb, its main dopant. On the other hand, it is also a hard task to obtain high Pb-free 2223 amounts, even

We investigated the magnetic, thermal and resistive properties of PrT 2 B 2 C ( T = Co , Ni ) and their solid solutions Pr 1− x Dy x T 2 B 2 C. These compounds behave as normal metallic paramagnets at higher temperatures. At lower temperatures, the

Publikováno v: Physica C: Superconductivity. 354:467-471

The effects of the precursor powder on Bi-2223 phase formation and the superconducting properties of Ag sheathed Bi-2223 tapes were studied. Three precursors were prepared. One was made by the “one-powder” method and the other two were prepared b

Publikováno v: IEEE Transactions on Appiled Superconductivity. 9:2573-2576

The effect of preparation of precursor powders on the formation of Bi-2223 phase and critical current density (J/sub c/) of OPIT tapes, was studied. The precursors were prepared by "one-powder" and "two-powder" methods. The results indicate that a su
