✦ Synopsis

Volume III/27 covers the magnetic properties of inorganic compounds based on transition elements. It can therefore be considered as a supplement to volumes III/4 and III/12 "Magnetic and other properties of magnetic oxides and related compounds" which appeared in 1970 and in the period 1978 - 1982 respectively. In a way this volume also forms a counterpart to volume III/19, in which the magnetic properties of met- als, alloys and metallic compounds are compiled. The first subvolume, III/27a, which appeared in late 1988, deals with the magnetic properties of pnictides and chalcogenides which contain 3d elements. Subvolume III/27d treats oxy-spinels. In the present subvolume III/27e oxidic compounds with the garnet structure are considered; they include both iron and non-iron substances. Physical and chemical properties which are of interest in connection with the magnetism of the garnets, have been given the necessary attention. Lists of iron and non-iron garnets help the user of this subvolume to find the substance he is interested in, and which are to be found in various parts of volumes III/4, III/12 and III/27.
