EuCu2As2 is argued to crystallize in the locally non-centrosymmetric P4/nmm structure, with a phonon anomaly near 165 K that may signal an electronic density wave instability.

Evidences for local non-centrosymmetricity and strong phonon anomaly in EuCu2As2: A Raman spectroscopy and lattice dynamics study
EuCu2As2 is argued to crystallize in the locally non-centrosymmetric P4/nmm structure, with a phonon anomaly near 165 K that may signal an electronic density wave instability.
