An Introduction to Crystal Field Effects in Magnetism,tom or ion. The energies of the various states may be expressed in terms of sums and differences of two electron coulomb and exchange integrals.[4,5] These integrals are usually parameterized in terms of either the Condon and Shortley or Racah interelectronic repulsion parameters.

Structural Characteristics and Rapid Solidification of Nd2Fe14B-Type Permanent Magnet Materials,rigonal prisms formed by each boron and its six nearest-neighbor iron atoms. A genuine departure from traditional sintering methods, melt spinning has emerged as a commercially viable means for producing magnets principally comprised of Nd.Fe.B-type compounds.

,The M?ssbauer Effect and its Application to Hard Permanent Magnetic Materials,sis techniques which may be used to extract the maximum amount of information from complex spectra such as those shown in Figure 1. Finally, the last section will review the application of iron-57 M?ssbauer spectroscopy to the R.Fe.B hard permanent magnetic materials. Pertinent studies with other M?ssbauer isotopes will also be discussed.

An Outline of the Prehistory of Magnetism,d superstitions prevented, for a very long time, the development of magnetism into a modern science. Indeed more than ten centuries passed between the discovery of the characteristics of magnetic materials and their practical application. In Europe, Aristotle blocked any progress for many centuries
