Abstrakt

The present article is devoted to a new low-temperature phase transition found at about T _pt = 84 K in the layered RbIn(MoO₄)₂

crystal. This phase transition is well proved by dynamical mechanical

analysis through anomalies in the temperature behaviour of both real and

imaginary parts of the Young's modulus. From the polarizing microscope

observations it was found that below T _pt the

ferroelastic phase disappears. This transition has also been seen

through strong changes in the shape of the electron paramagnetic

resonance lines. EPR studies, performed in the liquid nitrogen

temperature, yield evidence of strong rebuilding of the crystal unit

cell in comparison with that of the high temperature paraelastic phase.
