The memory effect in Eu2(MoO4)3 single crystals exposed to high hydrostatic pressure

Abstract

The influence of high-pressure hydrostatic compression and subsequent annealing on the structural properties of β’-phase single crystals of europium molybd ate was studied by IR spectroscopy and X-ray diffraction. It was demonstrated that after compression, the IR spectra exhibit drastic changes and do not depend on the initial crystallographic orientation of a single crystal. The high-pressure compression of single crystals followed by their annealing was found to result in the formation of β’-Eu2(MoO4)3 single crystals with the same crystallographic orientation as that of the initial samples.
