G. Ilonca et al., SUPERCONDUCTING, MAGNETIC AND NORMAL-STATE PROPERTIES IN BULK (BI1.6PB0.4)(ST1.8 BA-0.2)CA-2(CU1-XCRX)(3)O-Y, Physica. C, Superconductivity, 235, 1994, pp. 1391-1392
The electrical resistivity, the, hole concentration n(H)V(o) per Cu-si
te, a.c susceptibility and X-ray diffraction for (BiPb)-(SrBs)-(CuCr)-
O superconductors has been measured. Near T-c paracondnctivity studies
shows a 2D to 3D crossover in x=O and only a 2D character in the x no
t equal 0 samples. The n(H)V(o) is found to be linear vs. T for all Cr
dopped samples. Two subnetworkers with different intergrain coupling
strength were found.
