“…Later, this method was also used also for the analysis of different continuous, structural phase transitions (for example permutational, displacive, magnetic or quadrupolar types). The examples of their works may be found in [4][5][6][7][8][9][10][11][12][13][14]. Continuous (or semi-continuous) phase transitions, for example, in crystals, occur when under certain circumstances occur (e.g.…”

Abstract:In this paper we focus on the new version of computer program MODY for calculations of symmetryadapted functions based on the theory of groups and representations. The choice of such a functional frame of coordinates for description of ordered structures leads to a minimal number of parameters which must be used for presentation of such structures and investigations of their properties. The aim of this work is to find those parameters, which are coefficients of a linear combination of calculated functions, leading to construction of different types of structure ordering with a given symmetry. A spreadsheet script for simplification of this work has been created and attached to the program.

“…The method introduced at first by E.F. Bertaut and developed intensively recently [1], [2] works under the assumption that the symmetry change in phase transition preserves the group-subgroup relation (it means it is the continuous or "semicontinuous" phase transition) and that the "property" under consideration is localised on some sets of equivalent positions in the crystal initial phase.…”
