Spectral origin of the colossal magnetodielectric effect in multiferroic DyMn2O5
A. B. Sushkov, Ch. Kant, M. Schiebl +8
The origin of the colossal magnetodielectric effect in DyMn2O5 [1] has been an outstanding question in multiferroics. Here, we report the activation of the electric dipole mode at…
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…
Wüstite: Electric, thermodynamic and optical properties of FeO
F. Schrettle, Ch. Kant, P. Lunkenheimer +3
We report on a systematic optical investigation of wüstite. In addition, the sample under consideration, Fe0.93O, has been characterized in detail by electrical transport, dielectr…
Light-matter interaction in antiferromagnets: the exchange-induced magnetic dipole mechanism
M. V. Eremin, M. A. Fayzullin, Ch. Kant +2
We propose a novel mechanism for exchange-induced exciton-magnon absorptions via hopping between two antiferromagnetically coupled sites and a simultaneous magnetic dipole transiti…
Universal exchange-driven phonon splitting in antiferromagnets
Ch. Kant, M. Schmidt, Z. Wang +4
We report a linear dependence of the phonon splitting Δωon the non-dominant exchange coupling constant J_{nd} in the antiferromagnetic transition-metal monoxides MnO, FeO, CoO, NiO…
Improvement of superconducting properties of FeSe0.5Te0.5 single crystals by Mn substitution
A. Günther, J. Deisenhofer, Ch. Kant +3
We report on structural, susceptibility, conductivity, and heat-capacity studies of FeSe0.5Te0.5 single crystals with 2% substitution of Mn for Fe. Mn-doped samples show a higher o…
