概要

• 論文の詳細を見る

• The structures of RNbO_4 (rare-earth orthoniobate) single and twinned crystals have been studied in detail : (i) High temperature phase is scheelite structure (S. G. I4_1/a) and low temperature phase is monoclinic scheelite structure (S. G. I2/c= I2/a) ; (ii) Shuffles of all the constituent atoms are needed in twinning ; (iii) The mechanical twins in their crystals are defined as a twin of the third kind. All the domain walls of RNbO_4 crystals are the W' walls of the ferroelastic species 4/mF2/m proposed by Sapriel.
