Abstract

The ferroelastic domain structure of the perovskite-type layer crystals (C_nH_2n+1NH₃)₂MCl₄ (n=1,2,3 ; M=Cd,Mn) was observed and investigated in detail by means of a polarizing microscope. The orientation of the domain walls in the orthorhombic room temperature (ORT) phase has been determined. Temperature-dependent evolution of ferroelastic domain structure of (C₂H₅NH₃)₂MnCl₄ was studied through a ORT → tetragonal high temperature (THT) → ORT cycle. As the temperature approaches 155°C, the domain-wall density increases but ferroelastic-paraelastic phase transition seems to be impeded by inherent thermal decomposition at the surface.
