We generate frequency-tunable narrow-band intense fields in the terahertz (THz) range by
optical rectification of a temporally modulated near-infrared laser pumping a nonlinear …

The detailed optical properties of BaFe 2 As 2 have been determined over a wide frequency
range above and below the structural and magnetic transition at TN≃ 138 K. A prominent in …

We report inelastic light-scattering experiments on CaFe 2 As 2 in the temperature range of
4–290 K. In in-plane polarizations two Raman-active phonon modes are observed at 189 …

The cubic antifluorite K 2 IrCl 6 has recently garnered renewed attention due to its relevance
to Kitaev magnetism. Combining Raman spectroscopy with numerical calculations, we …

The temperature dependence of ab-plane optical conductivity of CaKFe 4 As 4 has been
measured below and above its superconducting transition temperature T c≃ 35.5 K. In the …

Magnetic materials having competing, ie, frustrated, interactions can display magnetism
prolific in intricate structures, discrete jumps, plateaus, and exotic spin states with increasing …

Magnetic and vibrational excitations in SrCu 2 (BO 3) 2 are studied using Raman
spectroscopy at hydrostatic pressures up to 34 kbar and temperatures down to 2.6 K. The …

We report on optical spectroscopy on the lacunar spinels GaV 4 S 8 and GeV 4 S 8 in the
spectral range from 100 to 23 000 cm− 1 and for temperatures from 5 to 300 K. These …

The effect of K, Co, and P dopings on the lattice dynamics in the BaFe 2 As 2 system is
studied by infrared spectroscopy. We focus on the phonon at∼ 253 cm− 1, the highest …
