| Abstract: | The crystallographic symmetry of the charge-ordered Pr0.5Ca0.5MnO3 manganite is studied at ～98?K using convergent beam electron diffraction technique. These studies have revealed appearance of two different type of charge-ordered phases in different domains of the same grain. These correspond to be monoclinic and triclinic phases. These studies reveal that the symmetry of the charge-ordered phase is highly sensitive to the local strain conditions. |
