Título: | Hard X-rays magnetic EXAFS |
Autor: | Dartyge, E.; Baudelet, F.; Brouder, C.; Fontaine, A.; Giorgetti, C.; Kappler, J. P.; Krill, G.; López, María Francisca CSIC ORCID ; Pizzini, S. | Fecha de publicación: | 1-mar-1995 | Editor: | Elsevier | Citación: | Physica B: Condensed Matter 208-209: 751-754 (1995) | Resumen: | The results of a systematic study of Magnetic EXAFS at K edges of transition metals (TM) and L edges of rare earth (RE) compounds are presented. At the K edges of TM the magnetic EXAFS is in phase with the normal EXAFS in all studied cases and its intensity is related to the variation of the mean magnetization. At L edges, magnetic EXAFS is not correlated with the complex magnetic dichroism observed at the edge. By studying the phase difference between the magnetic and normal EXAFS, we observe that there exists an interplay between the contribution of the central atom (giving a contribution to the phase in quadrature with normal EXAFS) and the magnetic neighbours (giving a contibution in phase). Multiple excitations are frequently observed in the spectra with a greater sensitivity than in normal EXAFS. | Versión del editor: | https://doi.org/10.1016/0921-4526(94)00897-5 | URI: | http://hdl.handle.net/10261/169560 | DOI: | 10.1016/0921-4526(94)00897-5 | ISSN: | 0921-4526 |
