Growth of Superconducting La2−xSrxCuO4 Single Crystals
Published online by Cambridge University Press: 21 February 2011
Abstract
High quality large single crystals of La2−xSrxCuO4 were grown by the traveling solvent floating zone method(TSFZ method). The crystals up to about 6 mm diameter and 40 mm length were obtained. The composition of the grown crystals was uniform and was determined to be La1.86Sr0.14Cu0.97O3.89. The single crystals were superconductors with Tc=37.5K and δ Tc=1.1K, and had a significant anisotropy of the electrical resistivities at the non-superconducting state.
