Possibility of simultaneously incommensurate and ferroelastic phase in RbIn(MoO4)2 by EPR of Cr3+ ion

Abstract

EPR investigations of RbIn(MoO4)2 are presented. It is found that at TI = 163 K a phase transition from the prototypic to an incommensurate ferroelastic phase takes place. Below T = 150 K a transition from broad to narrow soliton limit is observed and the soliton density ns is equal to 0.45 at 139 K. [Russian Text Ignored.]
