Intermetallic Compounds Containing Lanthanides (Studies of Magnetic Anisotropy).
Abstract
The powerful permanent magnetism of certain rare earth intermetallics (e.g., SmCo5) is a consequence of the strong magnetic anisotropy in these materials. Both sublattices contribute to magnetic anisotropy. Usually the contribution of the rare earth predominates over that of its chemical partner, a d-transition element in systems of practical interest. The rare earth anisotropy has been treated by quantum mechanics and is shown to be a crystal field effect. The partner element anisotropy has been studied experimentally and the details partially revealed. Magnetic interactions have been studied in a number of systems, particularly those involving Mn. Details are provided in 18 papers published in the open literature. (Author)
