摘要：

We report on the interplay among the structural transitions, transport anomalies and superconductivity in (La1-xBax-ySry)2CuO4. Here the amount of doping is held at x = 0.0625 and the structural transition temperatures are controlled by a parameter y. The appearance of the low-temperature tetragonal phase and the depression of superconductivity correlate well, but unlike in (La1-xBax)2CuO4 the transport anomalies can be decoupled from the structural transition, implying the presence of a new instability in the electronic state. © 1990, Elsevier Science Publishers B.V.
