Hard Magnetic Alloys

Volume 19 of Group III (Crystal and Solid State Physics) deals with the magnetic properties of metals, alloys and metallic compounds. The amount of information available 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, III/19c, III/19d1, III/19d2, III/19e1, III/19e2 and III/19f1 have appeared. 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 subvolume of III/19g (Thin Films) and III/19h which covers the magnetic properties of liquid quenched alloys containing transition elements. This subvolume III/19i2 deals with the magnetic properties of hard magnetic alloys for permanent magnets. The large fields of both the well-known magnets based on 3d elements and the currently widely investigated alloys based on rare earth elements are covered. The relation between the permanent magnet properties and the various preparation techniques of the alloys has obtained special attention.
