LSAT (La0.294Sr0.706Al0.647Ta0.353O3) Single Crystal Substrate
Product Overview:
LSAT is a perovskite-structure mixed oxide crystal. It typically has a cubic structure and is widely used as a substrate for the epitaxial growth of high-temperature superconducting (HTS) films (like YBCO) and magnetic oxide films due to its excellent lattice matching.
