Correlation between Valence and Electronic Structure as Studied by Exafs in RM2X2 Compounds

  • Chapter
Book cover Theoretical and Experimental Aspects of Valence Fluctuations and Heavy Fermions

Abstract

In the RM2X2 materials (R = Rare Earth, M = Transition Metal, X = Si, Ge …) many changes from one ground state to another under the influence of physical or chemical pressure have been reported. Even moderate pressures or substitutions create large variations of the electronic properties which are therefore associated with small changes of the crystallographic characteristics. EXAFS (Extented X Absorption Fine Structure) may give information about the local environment of the R ion (pair correlation). Unfortunately, in such non cubic structures, atomic relaxations cannot be evidenced. However, some correlation can be established between the R valence and the (R−M) and (R−X) distances or overlap in the CeM2 Si2 system and in EuPd2 Si2 versus temperature. Recent results on XANES (X Absorption Near Edge Structure) of intermediate valence YbPd2Si2−xGex (0 ≤ x < 1) seem very promising to obtain local information on the chemical environment in such systems.
