Identification and mechanical control of ferroelastic domain structure in rhombohedral CaMn${}_7$O${}_{12}$

Renliang Yuan, Lian Duan, Xinyu Du +1

We report on observation of ferroelastic domain structure in single crystals of multiferroic CaMn${}_7$O${}_{12}$ at room temperature. Two types of ferroelastic domain wall are found,…
