RUI: Symmetry Analysis of Domains, Domain Pair, Domain Twins and Domain Walls

9510335 Litvin本项目是中国科学院本科院校研究项目的一部分，对二维晶体学及其应用领域做出了贡献。研究者将识别和确定畴孪和壁的对称性，对于铁弹性和磁性材料。他将使用国际晶体学表E卷，他是最近的合著者。这些边界对多畴铁弹性材料和磁性材料的物理性质有重要影响。这项理论研究属于本科院校研究项目，在宾夕法尼亚州立大学伯克斯校区进行。它属于晶体学领域，涉及对固体对称性的研究。特别地，这个项目处理铁弹性和磁性材料内部的两个单独的完美晶体域相遇的区域。这些边界对多畴材料的物理性质有重要影响。* * *

9510335 Litvin This project, part of the Research in Undergraduate Institutions program, contributes to the area of two dimensional crystallography and its applications. The investigator will identify and determine the symmetry of domain twins and walls, for both ferroelastic and magnetic materials. He will make use of Volume E of the International Tables of Crystallography, of which he was a recent co author. These boundaries have an important influence on the physical properties of multi-domain ferroelastic and magnetic materials. %%% This theoretical research, under the Research in Undergraduate Institutions program, takes place at the Burks Campus of Pennsylvania State University. It falls in the area of crystallography, which involves the study of symmetries in solids. In particular, this project deals with those regions inside ferroelastic and magnetic materials where two individual perfect crystalline domains meet. These boundaries have an important influence on the physical properties in multi-domain materials. ***
