remnant beam
1.LaAlO_3/BaTiO_3 superlattices prepared by laser molecular beam epitaxy(L-MBE)exhibits excel- lent electric properties with the remnant polarization of 25μc/cm~2.The interface structures of LaAlO_3/BaTiO_3 super- lattice is investigated by using small-angle X-ray diffraction(SAXRD)and reflection high-energy electron diffraction (RHEED)technologies.
