Diffusionless Phase Transitions in Oxides

The relative importance of oxides in the field of materials is increasing every year, all over the world. The new or renewed basic and technological interest of ferroelectrics, ferroelastics, piezoelectrics, modulated structures and high-Tc superconductors provides excellent and well-know examples for the growing attention attracted by this class of materials. Most of the properties of these compounds are related to a phase transition phenomenon, so that phase transitions in oxides are today of the largest interest.
