Ferroelastic domain walls are typically twin interfaces. They contain a multitude of emerging properties, including (super-)conductivity, polarity, optically activity, and photovoltaic properties and may contain a number of magnetic properties even when there is no magnetic element in the ferroelastic matrix. Current progress to determine these properties is reviewed. Local wall properties change a little if the domain walls are deformed, but external fields can shift the location of the wall. Mobile domain boundaries carry with them the locus of any emerging property. The double flexibility of functional domain walls and the possibility to move domain boundaries provide a new design concept for device manufacturing. Some potential avenues for device designs are discussed.

铁弹性畴壁作为多铁性器件的模板

铁弹性畴壁通常是双界面。它们包含多种新兴特性,包括(超)导电性、极性、光学活性和光伏特性,并且即使在铁弹性基体中没有磁性元素时也可能包含许多磁性特性。审查了确定这些属性的当前进展。如果畴壁变形,局部壁特性会发生一点变化,但外部场可以改变壁的位置。移动域边界带有任何新兴财产的所在地。功能畴壁的双重灵活性和移动畴边界的可能性为器件制造提供了新的设计概念。讨论了设备设计的一些潜在途径。
