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. ***

9510335这个项目是本科院校研究计划的一部分，对二维结晶学及其应用领域做出了贡献。对于铁弹性材料和磁性材料，研究人员将识别和确定磁畴孪晶和磁壁的对称性。他将利用他最近与人合著的《国际结晶学表格》E卷。这些边界对多域铁弹性和磁性材料的物理性质有着重要的影响。这项理论研究在本科生机构研究计划下，在宾夕法尼亚州立大学伯克斯校区进行。它属于结晶学领域，它涉及到对固体中对称性的研究。具体地说，这个项目涉及铁弹性和磁性材料中两个单独的完美晶区相交的区域。这些边界对多域材料的物理性质有着重要的影响。***
