Influence of pressure on the inhomogeneous mixed valent state in Eu3S4
Description
The 21.7 keV nuclear gamma resonance of 151Eu was used for studying the inhomogeneous mixed-valent compound Eu3S4 in the pressure range 0 to 15 kbar. At room temperature the activation energy for electron hopping between the crystallographically equivalent divalent and trivalent Eu sites was found to decrease with pressure by dEsub(a)/dP = -1.8 +- 0.3 meV kbar-1. No change of the mean valence of Eu with pressure was observed. (author)
