Relationships between structure and low-dimensional magnetism in fluorides.

The available models and experimental results used in the description of magnetic order phenomena have been recently summarized in several papers. Among the materials showing low-dimensional magnetism, fluorides are of great interest as they provide examples for most of the different theoretical models. This article emphasizes the relationships between crystallographic features and dimensionality of the magnetic interactions in fluorides. The involved compounds are characterized by rings, chains, layers and three-dimensional arrangements of fluorinated MF6 octahedra. Spin-flop and zero-point spin-reduction phenomena are also considered, as many fluorides exhibit these behaviors. [ABSTRACT FROM AUTHOR]
