LSAT (LaAlO₃)_0.3(Sr₂AlTaO₆)_0.7 is a newly developing, twin-free crystal with a perovskite structure. LSAT has an excellent lattice match with high-T_c superconductors and many oxide materials. LSAT has a lower melting point and can be grown by Czochralski technology at lower cost. Therefore, it is expected to replace LaAlO₃ and SrTiO₃ as a common single-crystal substrate for epitaxial oxide thin films used in magnetic, ferroelectric, and superconducting devices.
