Kramer doublets, phonons, crystal-field excitations and their coupling in Nd2ZnIrO6

27 Feb 2020 Singh Birender Vogl M. Wurmehl S. Aswartham S. Büchner B. Kumar Pradeep

We report comprehensive Raman-scattering measurements on a single crystal of double-perovskite Nd2ZnIrO6 in temperature range of 4-330 K, and spanning a broad spectral range from 20 cm-1 to 5500 cm-1. The paper focuses on lattice vibrations and electronic transitions involving Kramers doublets of the rare-earth Nd3+ ion with local C1 site symmetry... (read more)
