Session Abstract

Phase transitions are both of fundamental interest to crystallographers but are also of immense technical interest, for example ferroic materials undergo a large variety of phase transitions and also exhibit important physical properties, many of which are used in industries world-wide in the form of single crystals, ceramics and thin films. The study of crystallographic phase transitions provides useful ways to understand the origin of the properties, and thus to suggest new materials.

For all abstracts of the session as prepared for Acta Crystallographica see PDF in Introduction, or individual abstracts below. The session continues by MS101 (18b).
