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. |

First - Order Character of the a - B Transition muret Although Landau theory gives
a good description of the behavior of a - quartz , the parameters of Eq . ( 1 ) must
be deduced from experimental results . This is particularly the case for thermal ...

In solids , this will be decreased somewhat because of covalent bonding with the
ligands to give B ( solid ) = BB ( free ion ) where ß is the “ nephalauxetic ratio . ”
For divalent transition metal oxides and silicates a reasonable value for B is ...

This gives dSvib = Cyyd In V or , on integration , ASvib = Cvy In ( V / V ) Hence ,
we can estimate the vibrational entropy change from the molar volumes of low -
spin and high - spin FeO . At the high temperatures of the mantle , we can
assume ...
