Rare-earth based materials: Electronic structures and magnetic properties

摘要

The electronic structures and magnetic properties of some rare-earth-transition metal compounds having technical interest is analyzed. The exchange interactions of 4f-5d-3d type is discussed in correlation with crystal structure and transition metal partner. The contributions to 5d band polarization due to local 4f-5d and short-range 5d-3d exchange interactions are estimated. Finally we analyze the magnetic behaviour of transition metals in rare-earth compounds.
