磁畴壁挠曲磁电效应的对称性理论

Symmetry Theory of the Flexomagnetoelectric Effect in the Magnetic Domain Walls

Bogdan M. Tanygin

摘要:

局部挠曲磁电(A.P. Pyatakov,A.K. Zvezdin,2009)在对称性分析的基础上研究了立方六八面体晶体的磁畴壁(DW)中的效应。DW的磁对称性和电极化的强度分布类型之间有很强的联系。结果在DW手性范围内进行了系统化。结果表明,利用外加均匀电场可以在实验上检测到一种新型的局部挠曲磁电耦合。

英文摘要:

A local flexomagnetoelectric (A.P. Pyatakov, A.K. Zvezdin, 2009) effect in the magnetic domain walls (DWs) of the cubic hexoctahedral crystal has been investigated on the basis of a symmetry analysis. The strong connection between magnetic symmetry of the DW and the type of the distribution of the electric polarization was shown. Results were systemized in the scope of the DW chirality. It was shown, that new type of the local flexomagnetoelectric coupling can be experimentally detected using the external homogeneous electric field.
