This work provides a new theoretical approach based on group theory and graph theory to capture the intrinsic properties of crystalline materials upon deformation.

A phase transition in a jumping crystal is predicted with Molecular Dynamics. The resulting structure and the dynamics of the transition are verfied by TLS refinement against Powder diffraction data.

Robust control of magnetism in LaAO₃/BaTiO₃ (A = Fe, Mn, Cr) perovskite superlattices is realized. Not only magnetism switching but also spin polarized 2D electron gas are created by switching of the polarization. We demonstrate a powerful scheme to realize robust control of both magnetism and 2D electron gas. Our work points the direction of the further development of multiferroic field.

The defect structure of γ-Al₂O₃ produced from boehmite is described with the aid of antiphase and rotational boundaries. The kind of structure defects are concluded from the selected-area electron diffraction patterns. The defect density is quantified from the anisotropic broadening of diffraction lines in powder X-ray diffraction patterns using a computer routine based on the Debye scattering equation.

The temperature evolution of [CH₃NH₃][Co(COOH)₃] on a single crystal and the crystal structure determination of intermediate incommensurate phases of [CH₃NH₃][Co(COOH)₃] by means of neutron diffraction are presented.
