LSAT (LaAlO3)0.3 (Sr2AlTaO6)0.7   is a newly developing crystal  with perovskite structure and twin-free.  LSAT has excellent lattice match with high Tc superconductors and many oxide materials. LSAT has lower melting point and  can be grown by CZ technology at lower cost, therefore, it is expected to replace LaAlO3 and SrTiO3 as a common single crystal substrate for epitaxial oxide thin films for gain magnetic ferro-electronic and superconductive devices
