A correlation between the increase in the critical temperature (Tc) and the increase in the frequencies of the vibrational spectra of various perovskite-like high-Tc superconductors has been established empirically for the first time. On the basis of this correlation a new system (Υ, _x Scx) (Ba, _ Sr^,) 2σέ06 has been synthesized and analyzed. In this system Tc has been observed to increase at intermediate concentrations.
