Abstract

Compressive and expansive strain was induced into (Formula presented) thin films with (Formula presented) on (Formula presented) and (Formula presented) substrates, respectively. For the compressed films, the superconducting transition temperature (Formula presented) reached 44 K with (Formula presented) and 49 K with (Formula presented) and the (Formula presented) phase diagram did not show a local minimum at (Formula presented) the so-called (Formula presented) anomaly.” For the expanded films, we observed strong reduction of (Formula presented) We suggest that the absence of the (Formula presented) anomaly” in the compressed films is due to the c-axis expansion, as well as the in-plane compression, and suppression of the residual resistivity.
