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. |

ized by a modulated structure with a period incommensurate ( inc ) to that of the
quartz lattice . ( Dolino et al . , 1982 ) . Since its discovery , this inc phase has
been the subject of several investigations recently reviewed by Dolino ( 1986 ) .

A characteristic feature of these inc states is the existence of satellite peaks
around ordinary lattice Bragg peaks , observed in diffraction experiments with X -
rays , neutrons , or electrons . In conducting materials , the origin of these inc
phases ...
