Volume III/27 deals with magnetic properties of non-metallic inorganic compounds based on transition metal elements such as pnictides, chalcogenides, halides, borates, silicates and phosphates. Subvolume 27B covers the magnetic and related properties of lanthanide pnictides and chalcogenides (except oxides). During the last decades considerable progress in the research of these families of substances has been made which have been compiled in several parts. The first part B1 with a compilation of the properties of monopnictides was published earlier this year. This Part 27B2 covers the monochalcogenides. Volume B3 will cover the binary compounds of pnictides and chalcogenides.
