abstract = {From crystal structure, three types of translation and two
types of orientation domain boundaries are expected in
La2/3Ca1/3MnO3 as a result of phase transition. However, the
most easily observed domain boundaries in the bulk samples
are [1/2 1/2 1/2] translation boundaries ( or antiphase
boundaries) and 90 degrees domain boundaries, while the [1/2
0 1/2] and [0 1/2 0] translation boundaries were rarely
observed. In this paper, this phenomenon is explained by
considering the tilting modes of the oxygen octahedra in the
structure. We found that there is no distortion to the
nearby oxygen octahedra if the [1/2 1/2 1/2] translation
boundaries take the ( 010) boundary planes and the 90
degrees domain boundaries are in the {101} planes, making
them low-energy boundary planes and, thus, are easy to form.
On the other hand, the [1/2 0 1/2] and [0 1/2 0] translation
boundaries introduce a distortion in the oxygen octahedra,
which requires breaking the tilting modes in the boundary
areas and, therefore, they are high-energy boundary planes,
which are rarely observed. The above-expected results are
supported by our transmission electron microscopy data.},
