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. |

All of the predicted structures for the 3 : 1 phase differ from the one proposed by Wenk and Zhang ( 1985 ) for the y ... It is possible that 3 : 1 is always more stable than y , as the TA predicts ( Burton , 1987 ) , but that y is more ...
