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. |

Hopping mechanism of the intermediate polaron (Fe2+-Fe3+ pair with a
conducting electron). perature was 3.3 x 103 Qm. Resistivity in a perpendicular
direction was somewhat higher but showed a similar temperature dependence.
