Transport and magnetic properties in (Bi-1.6 Pb-0.4)(Sr1.8Ba0.2)Ca-2(Cu1-xCrx)(3)O-y bulk

High-T-c cuprates of "Bi-2223" bulk with Cr were prepared by the convention al solid-state reaction method. The samples have been investigated by elect rical resistivity, Hall, Nernst effects, AC susceptibility and thermopower measurements in mixed and normal state. The transport coefficients depend s trongly on the Cr contents in the samples. The anomalies are discussed in n ormal state in the framework of phase separation theory. The experimental d ata in the mixed state are in agreement with the predictions of the time-de pendent Ginsburg-Landau theory. (C) 2000 Elsevier Science B.V. All rights r eserved.
