Abstract
The temperature dependence of the thermoelectric power of simultaneous dopi ng of alkali elements i.e. Na at Ca and K at Sr site in the Bi -2212 system with the composition Bi2Sr2-xKxCa1-yNayCu2Oz where x=0.1 and y=0.1,0.2,0.3 ,0.4 labeled as KINI, KIN2, K1N3, K1N4 are studied: The T-C(0), varies from 63-67 K in all these new series of samples. The single phase Bi-2212 was f ound in all the compositions. The T-C(0), and thermoelectric power data wer e collected from 12-300 K. The data were analysed within the existing theor etical models.
