Thin films of BaTiO3 have been epitaxially grown on Pt(001)/MgO(100) substrates by reactive evaporation. Structural and electrical properties were investigated as a function of film thickness. In situ reflection high‐energy electron diffraction and

Epitaxial crystals of BaTiO3 have been grown by activated reactive evaporation. The ultra-thin crystal less than 100A thickness shows an elongation along the c-direction. The ferroelectric phase transition of the thin films is discussed in terms of t

Epitaxial crystals of BaTiO 3 with the thicknesses of 67 A, 230 A, 600 A and 1500 A were grown on SrTiO 3 substrates by activated reactive evaporation. The tetragonality of the crystal decreases with increasing thickness and remains in the temperatur

Structure analysis of K 3 H(SO 4 ) 2 was performed by X-ray diffraction experiments at various temperatures down to 27 K in order to investigate the hydrogen bond character in connection with the geometrical isotope effect. The hydrogen bond length R

Structural phase transition of K 3 D(SO 4 ) 2 was studied by X-ray scattering experiments, and new reflections were observed below T c =85 K. The space groups are A 2/ a ( Z =4) above T c and P 2 1 / a ( Z =4) below T c . The postulated structure of
