(La, Sr) (Al, Ta) O 3 is a relatively mature non-crystalline perovskite crystal, which is well matched with high temperature superconductors and a variety of oxide materials. It is expected that lanthanum aluminate (LaAlO 3) and strontium titanate (SrO 3) will be replaced in giant magnetoelectrics and superconducting devices in a large number of practical applications.
