Atomic displacements in ferroelectric trigonal and orthorhombic boracite structures

Abstract

New crystal-structure refinements of Pca 2 1 boracite, Mg 3 ClB 7 O 13 , and R ϵ c ericaite, Fe 2.4 Mg 0.6 ClB 7 O 13 , show that some boron and oxygen atoms are involved in the ‘ferro’ transitions as well as the metal and halogen atoms. The atomic displacements associated with the polarity changes are as large as 0.6Å.

Cluster molecular orbital description of the electronic structures of mixed-valence iron oxides and silicates

A molecular orbital description, based on spin-unrestricted X α-scattered wave calculations, is given for the electronic structures of mixed valence iron oxides and silicates. The cluster calculations show that electron hopping and optical intervalence charge-transger result from weak FeFe bonding across shared edges of FeO 6 coordination polyhedra. In agreement with Zener's double exchange model, FeFe bonding is found to stabilize ferromagnetic coupling between Fe 2+ and Fe 3+ cations.
