Electromagnons, magnons, and phonons in EuHoMnO
Zhenyu Chen, M. Schmidt, Zhe Wang +5
Here we present a detailed study of the THz and FIR response of the mixed perovskite manganite system EuHoMnO for holmium concentrations x = 0.1 and 0.3. We compare…
Orbital-selective metal-insulator transition and gap formation above Tc in superconducting Rb1-xFe2-ySe2
Zhe Wang, M. Schmidt, J. Fischer +5
We report on a hierarchy of temperatures Tc < Tgap < Tmet in superconducting Rb1-xFe2-ySe2 observed by THz spectroscopy. Above Tmet = 90 K the material reveals semiconducting chara…
Exciton-magnon transitions in the frustrated chromium antiferromagnets CuCrO2, alpha-CaCr2O4, CdCr2O4, and ZnCr2O4
M. Schmidt, Zhe Wang, Ch. Kant +7
We report on optical transmission spectroscopy of the Cr-based frustrated triangular antiferromagnets CuCrO2 and alpha-CaCr2O4, and the spinels CdCr2O4 and ZnCr2O4 in the near-infr…
Infrared phonons and specific heat in Ba3Cr2O8
Zhe Wang, M. Schmidt, A. Günther +7
We report on the phonon spectrum of Ba3Cr2O8 determined by infrared spectroscopy, and on specific heat measurements across the Jahn-Teller transition in magnetic fields up to 9 T.…
Singlet-triplet excitations and high-field magnetization in CuTe2O5
Zhe Wang, M. Schmidt, Y. Goncharov +6
By measuring the THz electron spin resonance (ESR) transmission spectra and high-field magnetization on the spin-gapped system CuTeO, we identified the singlet-triplet exci…
Optical conductivity of superconducting Rb2Fe4Se5
A. Charnukha, J. Deisenhofer, D. Pröpper +8
We report the complex dielectric function of high-quality nearly-stoichiometric Rb2Fe4Se5 (RFS) single crystals with Tc=32 K determined by wide-band spectroscopic ellipsometry and…
