Strontium tantalum lanthanum aluminate (La,Sr)(Al,Ta)O3 (LSAT) is a kind of more mature perovskite crystal, which is well matched with high-temperature superconductors and various oxide materials. It is expected to be as the substitute of the lanthanum aluminate (LaAlO3) and strontium titanate (SrTiO3), which will be used in giant magnetoelectric and superconducting devices in a large number of practical applications. Get a Quote Now!
