This book presents advances in the field of rare-earth (R) – transition metal (M) – boron compounds with extensive references. Since titanium and scandium do not form compounds with rare-earths, the Sc/Ti-M-B series are additionally presented. In each chapter the crystal structures, the complex physical properties as determined from neutron diffraction, magnetic measurements, resonance studies, transport properties and band structure calculations are critical analyzed. The models used in describing the experimental evidence are also presented. Tables with the main properties of the R-M-B compounds are given and representative data are illustrated in figures. In this way, the book provides state-of-the art knowledge and a valuable analysis of up-to-date results in the field. The technical applications, as permanent magnets, thermoelectric and magnetocaloric devices, hydrogen storage are also highlighted along with the authors insights into future directions in the field. The book is ofinterest for scientists involved in the development of the field as well as those working in the technical uses of rare-earth compounds.

The Landolt-Börnstein Volume 27 deals with the magnetic properties of non-metallic inorganic compounds based on transition elements, such as there are pnictides, chalcogenides, oxides, halides, borates, and finally phosphates and silicates, the latter presented in this subvolume I. A preliminary survey of the contents of all subvolumes that have already appeared or have been planned to appear is printed on the inside of the front cover. The silicates are very complex systems, intensively studied in literature. They cover large classes of minerals as well as synthetic samples. In analyzing their magnetic and magnetically related properties we essentially followed the classification given by the Mineral Reference Manual (E. H. Nickel, N. C. Nickols, Van Nostrand Reinhold, 1991) or other more recent classifications. Individual chapters are dedicated to orthosilicates, sorosilicates, cyclosilicates, inosilicate, phyllosilicates and tectosilicates. Due to the huge amount of data these chapters had to be spread over several subvolumes I1, I2, etc. . - In each chapter the different groups of minerals and synthetic silicates were distinctly analyzed in various sections. For each group, additional silicate minerals, more recently reported, as well as synthetic samples having related compositions and/or crystal structures were also considered. The silicates included in each section were firstly tabulated, mentioning their compositions. The solid solutions between the end member compounds were also described. The space groups and lattice parameters for most silicates were tabulated.

The magnetic properties of silicates and phosphates are compiled in subvolume 27I. While subvolumes 27I1, 27I2, 27I3, 27I4, 27I5 and 27I6 (already published) deal with orthosilicates, sorosilicates, cyclosilicates, inosilicates, and phyllosilicates, respectively, the present subvolume 27I7 deals with phosphates.

Subvolume 27I6 has been split in three parts α, ß  and  γ. Further subvolumes will be dedicated 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, X-ray absorption spectroscopy, transport properties, dielectric and optical data are reviewed.
