| Popis: | The electron microscopic study was performed on an orthorhombic BaEu 2 Mn 2 O 7 phase. The electron diffraction patterns of this phase showed some series of superlattice spots such as h 0 0 ( h = odd), h k 0 ( h , k = odd) and h 0 l ( h , l = odd) that were forbidden for face centered cell. A possible space group P112 1 /m (11) was derived from the reflection conditions. And then, a superstructure of this phase was discussed in this paper. |
