Phase transitions in barium–strontium titanate films on MgO substrates with various orientationsA comparative study of the lattice dynamic upon phase transitions in a polycrystalline Ba 0.8 Sr 0.2 TiO 3 (BST) film on a Pt substrate and in epitaxial BST films grown on various sections of an ...
Below the tetragonal to orthorhombic phase transition in barium titanate, visible light from a laser beam was observed to produce a Laue-type spot diffraction pattern in the forward direction. The pattern produced has six-fold rotational symmetry about the forward direction and is seen only after ...
