Аннотация: Single crystals of (ND4)(2)MoO2F4 containing 95% deuterium were produced by repeated recrystallization of (NH4)(2)MoO2F4 in heavy water. The effect of deuteration on the parameters of successive phase transitions was investigated by differential scanning microcalorimetry and polarization optics. X-ray analysis of the original and dПоказать полностьюistorted phases was performed. It was found that deuteration does not change the sequence of crystal phases typical for (NH4)(2)MoO2F4, but leads to a shift in the phase transition Cmcm -> Pnma towards the tricritical point. The mechanism of phase transitions in (ND4)(2)MoO2F4 was associated with both the ordering and the displacement of atoms. (C) 2016 Elsevier Masson SAS. All rights reserved.
