摘要：

The effect of the replacement of strontium ions by lithium ions on the T(c)s of liquid-nitrogen-quenched "2212" bismuth superconductors processed at 700-degrees-C is studied. As is the case for the exchange of copper ions by lithium ions, the Li/Sr exchange produces a linear (with respect to the amount of Li substitution) increase in the T(c)s. The similarity between the increases for the Li/Cu and Li/Sr exchanges points to the increases in the T(c)s being due to the effects of hole creation resulting from the non-isovalent ionic substitutions.
