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