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. |

Hyperfine Fields and Spin Frustration A slightly different picture of the magnetic
ordering emerges from a study of the low - temperature Mössbauer spectra in the
range 4 to 120 K ( Kan et al . , 1988 ) . The evolution of the hyperfine fields at the

An additional classification is appropriate : ordinary and reentrant spin glasses .
In ordinary spin glasses no long - range order is established . Instead , short -
range correlations become stronger and stronger when the temperature is
lowered .
