Optical Study of Archetypical Valence-Fluctuating Eu Systems
Optical Study of Archetypical Valence-Fluctuating Eu Systems
We have investigated the optical conductivity of the prominent valence fluctuating compounds EuIr2Si2 and EuNi2P2 in the infrared energy range to get new insights into the electronic properties of valence fluctuating systems. For both compounds we observe upon cooling the formation of a renormalized Drude response, a partial suppression of …
