 note = {We have succeeded in synthesizing high-Tc cuprates of YBa2-xSrxCu3O7-y up to x = 2.0 with alkali
metal hydroxides beyond the ever reported Sr solubility limit of x = 1.0 in a simple solid-state reaction
method. The X-ray diffraction experiment indicates that Sr substitutions cause the structural change at
room temperature from a tetragonal to an orthorhombic structure between x = 1.6 and x = 1.8. We
observed superconducting transitions in the temperature dependence of resistivities, and that Tc
decreases with Sr substitutions.},
