Interstitial Nitrogen, Carbon, and Hydrogen: Modification of Magnetic and Electronic Properties

  • Chapter
Interstitial Intermetallic Alloys

Part of the book series: NATO ASI Series ((NSSE,volume 281))

Abstract

It is shown how the electronic and magnetic properties of rare-earth transition-metal intermetallics are modified by interstitial atoms. On an introductory level and starting from illustrative physical ideas we relate band structure, statistics, and electrostatic crystal field effects to the intrinsic properties magnetic moment, Curie temperature, and magnetocrystalline anisotropy. We discuss how the permanent magnetic properties of Sm2Fe17 and other intermetallics are improved upon interstitial modification, and put particular weight on recent developments such as spin-fluctuation theory and screening of crystal-field charges.
