Abstract
Large bulk single crystals of the Sr2CuO2Cl2 compound with dimensions of 15 x 6 x 4 mm(3) have been grown directly from the melt by the floating-zone method using a light-image furnace. The optimal growth conditions are found in a mixed atmosphere of 0.2 bar oxygen and 1.2 bar argon. Results of the characterisation have revealed thr high quality of the as-grown crystals. Furthermore, a possible congruent route of formation from the melt as well as the chemical stability of this compound is discussed.
