Stress-induced nematicity in EuFe2As2 studied by phononic Raman spectroscopy

W. -L. Zhang, Athena S. Sefat, H. Ding +2

We use polarized Raman scattering to study the structural phase transition in EuFe2As2, the parent compound of the 122-ferropnictide superconductors. The in-plane lattice anisotrop…
