摘要：

An electron diffraction and microscopy study of the BaxLa1-xFeO3- x 2 ( 1 2 ≤ x ≤ 2 3) samples to be formed by three-dimensional microdomains. The unit cell corresponding to each domain is related to the cubic perovskite structure by the expression ac × ac × 2ac, ac being the cubic perovskite unit cell parameter. A structural model in which octahedral and square pyramidal layers intergrow in an ordered way following the double axis is proposed. © 1991.
