摘要：

Compositional variations in BaMnO3-y perovskite-related materials in the 0.08 less-than-or-equal-to y less-than-or-equal-to 0.12 range are accommodated either by means of the formation of an ordered rhombohedral phase for y = 0.10 (15R type) or by means of disordered intergrowths of both 15R and a new polytype of nominal composition BaMnO2.928. This phase can be described as formed by 21 layers per unit cell, following the stacking sequence . . . (chhhhhh)3 . . . . (C) 1994 Academic Press, Inc.
