Relationship between orthorhombic, rhombohedral and cubic perovskite crystal structures
Relationships between orthorhombic, rhombohedral or cubic perovskite crystal structures were studied, by examining experimental results about manganites possess an ABO3 type perovskite crystal structure published last years. Sketch map of atom distribution about the three kind of ABO3 type perovskite crystal structure, and the relationships between them were given. It is pointed out that the magnitude of orthorhombic or rhombohedral structures perovskite crystal structures depart from cubic structure are very small, and a equivalent cubic cell about the three perovskite crystal structures can therefore be used to research some physical problems about perovskite manganites.
