The temperature dependence of the debye-waller-factor in barium titanate
The results of recent investigations of the crystal structure of BaTiO 3 in the cubic, tetragonal, and rhombohedral phase are in accordance with an order-disorder-model, described either by 'split-atoms' or a double well potential. The model yields quantitatively the temperature dependence...

in the cubic, tetragonal, and rhombohedral phase are in accordance with an order-disorder-model, described either by 'split-atoms' or a double well potential. The model yields quantitatively the temperature dependence and the anisotropy of the thermal vibrations. |
