Title: Galvanomagnetic effects in Gd and Zn-substituted Bi{sub 2}Sr{sub 2}Ca{sub 1{minus}x}Gd{sub x}(Cu{sub 1{minus}y}Zn{sub y}){sub 2}O{sub 8+{delta}}

Abstract

The authors had performed a study on magnetoresistivity Hall, Nernst and Seebeck effects in the mixed and normal state for Bi2212 bulk with Gd (0 {le} x {le} 0.50) and Zn (0 {le} y {le} 0.03) prepared by the conventional solid state reaction method in magnetic fields between 0 and 5 T and in the temperature range 5--300 K. The critical temperatures, the Hall concentration, the Nernst and Seebeck coefficients depend strongly on the Zn and Gd contents in the samples. Also, they have found an anomalous suppression of superconductivity at x = 0.30--0.35 and y = 0.025--0.030, when the hole concentration per Cu is p {approximately} 1/8 and the transport properties exhibit less metallic behavior than usual. There is a possibility that a kind of order of holes and/or spins is stabilized owing to pinning by Zn, as in the La-based cuprate.
