Fecha de publicación: | feb-2007 | Editor: | American Institute of Physics | Citación: | Aip Conference Proceedings 882(1): 484-486 (2007) | Resumen: | We report on a transition metal contribution to the rare-earth L2-edge XMCD spectrum of intermetallic rare-earth - transition metal compounds (R-T). The shape and location of this contribution is independent on both the specific rare-earth and the specific 3d metal in the compound. The evolution of the signal with the 3d content indicates that the signal is proportional to the number of T neighboring atoms around the absorbing R atom. In addition, comparison between Fe and Co Laves compounds indicates that the signal also resembles the magnetic moment of the T metal. Comparison with other R:T series shows that the presence of a T contribution is not a particularity of Laves phases but a general result. | Descripción: | 3 pages, 3 figures.-- X-Ray Absorption Fine Structure-XAFS13: 13th International Conference.-- et al. | Versión del editor: | http://dx.doi.org/10.1063/1.2644566 | URI: | http://hdl.handle.net/10261/19305 | DOI: | 10.1063/1.2644566 | ISSN: | 0094-243X |
