Foglio Física, Astronomía y Matemáticas ESR Crystal field We consider the ESR of Co2+ in different environments: in an regular octahedron (Co2+ in a MgO crystal),in a deformed octahedron (Co2+ in single crystals and powder samples of NH4NiPO4.6H2O) or in a trigonalbipyramid (Co2+ in powders of Co2(OH)PO4 and Co2(OH)AsO4). We study the effect of the non-cubic crystalfields in the ESR of Co2+ in the deformed octahedron, by employing the normal modes of this structure tosimplify the systematic study of the effect of these fields. A similar study was done for the deformed trigonalbipiramid, and it was necessary to derive the normal modes of this complex that are relevant to our problem. 2006 artículo científico 0103-9733 https://www.redalyc.org/articulo.oa?id=46436109 en http://www.redalyc.org/revista.oa?id=464 Brazilian Journal of Physics application/pdf Sociedade Brasileira de Física Brazilian Journal of Physics (Brasil) Num.1A Vol.36 |
