"Raman scattering study of NaFe0.53Cu0.47As." <i>Physical Review B,</i> 98, no. 9 (2018) American Physical Society: https://doi.org/10.1103/PhysRevB.98.094512.https://hdl.handle.net/1911/103333We use polarization-resolved Raman scattering to study lattice dynamics in NaFe0.53Cu0.47As single crystals. We identify four A1g phonon modes, at 126, 172, 183, and 197 cm−1, and four B3g phonon modes at 101, 139, 173, and 226 cm−1(D4h point group). The phonon spectra are consistent with the Ibam space group, which confirms that the Cu and Fe atoms form a stripe order. The temperature dependence of the phonon spectra suggests weak electron-phonon and magnetoelastic interactions.engArticle is made available in accordance with the publisher's policy and may be subject to US copyright law.
