抄録

New low temperature phases of Sr₂Ta₂O₇ and Sr₂Nb₂O₇ were found by electron microscopy. Sr₂Ta₂O₇ undergoes a structural phase transition at about 170°C to a superlattice structure belonging to the monoclinic system with space group P2₁⁄m, accompanying the appearance of characteristic twin and antiphase domains. Sr₂Nb₂O₇ has an incommensurate phase below about 220°C with an irrational lattice modulation in the [100] direction and an intricate fine domain-like texture.
