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. |

In such a cluster , Fe - Fe bonding occurs through an overlap of the Fea ( 125Fe (
tze ) orbitals . Provided the Fe - Fe separation is less than 2 . 95 Å , the overlap
results in a cluster molecular orbital analog of the narrow Fe ( 3d ) band . If the Fe

The instrumental resolution corresponds to cluster sizes above 900 A . Within
these limits no broadening was observed for type I samples , while for type II
samples the cluster size is roughly 450 ( + 100 ) Å . In phase III the cluster size
