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. |

One experimental possibility is to test whether structural data are in favor of a
disordered or of an ordered structure for the B phase . A first test by Young ( 1962
) with X - ray diffraction concluded that the B phase was a normal ordered crystal

The role of the disordered phase is thus very similar to that of a basic polytype ,
which might shed some light on the fact that even highly disordered polytypes
might represent thermodynamic phases . Our experimental results seem to give ...
