Abstract

Mössbauer and X-ray absorption spectroscopic studies clearly establish that the system EuNi2P2 (crystallizing in the ThCr2Si2 structure) is a fluctuating-valence system with nearly temperature-independent average valence, ν̅≈2.6 in the temperature interval 300-77 K. The material EuCo2P2 is normal with the Eu ions in a stable divalent state.
