Abstract

Binary alloys between the rare earth metals (elements) and metals from the first or second transition series elements exhibit a large range of magnetic properties. Their application in the field of permanent magnets has grown rapidly. Many alloys of the rare earths with transition series elements have properties suitable for magnetic refrigeration. Preparation of these alloys in high purity and in forms suitable for refrigeration devices presents many problems. Trade offs between purity and magnetic properties must be made to obtain structurally sound refrigeration materials at a reasonable cost. Laboratory methods used to prepare and study these alloys will be presented. Large scale methods to produce permanent magnet materials have been developed. These methods and their possible application to magnetic refrigeration alloys will be presented.
