In some heavy rare-earth compound quadrupolar ordering has been observed. The poster shows an example of symmetry analysis of quadrupolar ordering and the accompanying structural and magnetic phase transitions (in CeB₆ and DyB₂C₂ compounds) using MODY_win program. Such symmetry analysis is very useful because it can give both - hints and model verification for experimental investigations of quadrupolar ordering. Without the symmetry analysis the interpretation of experimental results encounters considerable difficulties.

Poster also presents a short introduction and an example of quadrupolar moment order visualisation, by TENSOR_vis program. The proper description of visualisation is important because in many papers the problem has been oversimplified and the graphical presentation is not adequate.
