Abstract:
The compounds composed of transition metal cations and pnictide anions provide a rich platform for studying novel physical phenomena. Here we report on the observation of a phase transition at ∼ 70 K and 145 K in layered compound EuCu 4 As 2 and SrCu 4 As 2 , respectively. from both the transport and heat capacity. The thermal expansion measurements show that the variation of the lattice parameters (Δ L b / L ab ) around T P is much less than that for a typical crystalline phase transition. Our experimental results reveal that the transition in EuCu 4 As 2 and SrCu 4 As 2 should be driven by subtle structural-distortion.
