Volume 19 of Group III (Crystal and Solid State Physics) deals with the magnetic properties of metals, alloys and metallic compounds. The amount available of information in this field is so substantial that several subvolumes are needed to cover it all. Subvolumes III/19a through III/19f treat the intrinsic magnetic properties, i.e. those magnetic properties which depend only on the chemical composition and the crystal structure. So far, subvolumes III/19a, III/19b and III/19c have appeared. Subvolume III/19e is concerned with the magnetic data of the metallic compounds of rare earth elements with main group elements. It is divided into two parts. Part III/19e2 came out last year; part III/19e1 is presented herewith. Data on the properties that depend on the preparation of the samples measured, as for instance, thin films, amorphous alloys or the magnetic alloys used in technical applications, are being compiled in the last subvolumes of III/19: III/19g and III/19h, of which III/19g has already appeared.
