Structural and Magnetic Phase Transitions in MineralsThis volume in Advances in Physical Geochemistry presents the latest synthesis of theory and experimental data pertaining to structural and magnetic phase transitions in a variety of geochemically important minerals. The book is the first to cover the impact of this rapidly progressing area of solid state physics in earth sciences and reflects its growing significance for mineralogy and petrology. |

Landau theory can describe both first- and second - order symmetry - breaking
transitions , but fluctuation effects are outside its range of validity . For a transition
that conserves the number of atoms in the unit cell , the order parameter is ...
