Abstract

We report the successful growth of a large (Ca$_{x}$La$_{1-x}$)(Ba$_{1.75-x}$La$_{0.25+x}$)Cu$_{3}$O$_{y}$ (CLBLCO) single crystal. In this material, $x$ controls the maximum of Tc ($T_{c}^{\max}$), with minimal structural changes. Therefore, it allows a search for correlations between material properties and $T_{c}^{\max}$. We demonstrate that the crystals are good enough for neutron scattering and cleave well enough for Raman scattering. These results open new possibilities for cuprate research.
