The magnetic properties of silicates and phosphates are compiled in subvolume 27I. While subvolume 27I1 (already published) deals with orthosilicates, the present subvolume 27I2 deals with sorosilicates. Further subvolumes are dedicated to other types of silicates (cyclosilicates, inosilicates, phyllosilicates, tectosilicates) and to phosphates. - Silicates are very complex systems, covering large classes of minerals as well as synthetic samples. Their crystal structure is discussed and atomic positions are given. In addition to magnetic properties, results of neutron diffraction studies, nuclear gamma resonance, nuclear magnetic resonance, transport properties, dielectric and optical data are reviewed.

From the contents Magnetic and related properties of silicates and phosphates.- Eight chapters for different types of cyclosilicates.- Figures, tables and references for each chapter.- Two indexes of substances for element systems and mineral names.

The magnetic properties of silicates and phosphates are compiled in subvolume 27I. While subvolumes 27I1, 27I2 and 27I3 (already published) deal with orthosilicates, sorosilicates and cyclosilicates, respectively,. the present subvolume 27I4 deals with inosilicates. Further subvolumes are dedicated to other types of silicates (phyllosilicates, tectosilicates) and to phosphates. - Silicates are very complex systems, covering large classes of minerals as well as synthetic samples. Their crystal structure is discussed and atomic positions are given.

The new profile of modern hard magnetic materials is supported by the recent conjunction of the nanocrystalline state responsible for the extrinsic magnetic properties with on the one hand the existence of the two families of intermetallic compounds possessing the three intrinsic magnetic characteristics required for high performance magnets (strong uniaxial magnetocrystalline anisotropy, elevated Curie temperature, and important magnetic moment) and on the other hand the opportunities of adapting the global magnetic characteristics to the profile of specific demands. The new generation of those remarkable alloys covers rare-earths (R = Nd, Pr, Sm) and 3d transition metals (T = Fe, Co) alloys for the former and 3d transition metal (Fe, Co) with 4d (Pd) and 5d (Pt) transition metals for the latter. Besides the use of these alloys in many components of electromechanical and electronic devices, their high anisotropy values made these compounds prominent candidates for ultra high density recording applications due to the feasibility of smaller grains still magnetically thermally stable.
