| 中文摘要 | a new orthorhombic phase of baeu2mn2o7 with the space group of ccmm (no.63) was identified for single crystals after heat treatment and its crystal structure was determined by single crystal x-ray diffractometry. the volume of the unit cell has twice the fundamental tetragonal cell and corner-shared mno6 octahedra are slightly distorted and mn-o-mn angle between the neighboring octahedra tilts with an angle by around 3 degrees from b-axis. it is concluded from the results of the heat treatment of single crystals at various temperatures that this orthorhombic phase changes into a tetragonal one with superstructure (p4(2)/mnm) at 402 k and changes once more into the fundamental tetragonal phase (i4/mmm) above 552 k. the tetragonal phase with superstructure which has been expected to be an unstable one is stable between the two temperatures. |
