Structural phase transition below 250 K in superconducting K $_{0.75}$ Fe $_{1.75}$ Se $_{2}$

A. Ignatov, A. Kumar, P. Lubik +5

Vibrational properties of iron-chalcogenide superconductor K $_{0.75}$ Fe $_{1.75}$ Se $_{2}$ with $T_{c} \sim$ 30 K have been measured by Raman and optical spectroscopies over temperatu…
