Zeeman and Davydov splitting of Frenkel excitons in the antiferromagnet CuBO
N. E. Kopteva, D. Kudlacik, D. R. Yakovlev +4
The optical spectra of antiferromagnetic copper metaborate CuBO are characterized by an exceptionally rich structure of narrow absorption lines due to electronic transition…
Magneto-electric properties and low-energy excitations of multiferroic FeCr2S4
A. Strinic, S. Reschke, K. V. Vasin +5
We report on the low-frequency optical excitations in the multiferroic ground state of polycrystalline FeCr2S4 in the frequency range 0.3-3~THz and their changes upon applying exte…
Sub-gap optical response across the structural phase transition in van der Waals layered α-RuCl
S. Reschke, F. Mayr, S. Widmann +7
We report magnetic, thermodynamic, thermal expansion, and on detailed optical experiments on the layered compound -RuCl focusing on the THz and sub-gap optical response acro…
Jahn-Teller induced nematic orbital order in tetragonal SrVO
J. Teyssier, E. Giannini, A. Stucky +3
Using high resolution X-Ray diffraction (XRD) on high purity powders, we resolved the structure and symmetry of the intriguing compound \svo from room temperature down to 2…
ESR evidence for partial melting of the orbital order in LaMnO below the Jahn-Teller transition
S. Schaile, H. -A. Krug von Nidda, J. Deisenhofer +3
We report on high-temperature electron spin resonance studies of a detwinned LaMnO single crystal across the Jahn-Teller transition at = 750 K. The anisotropy of t…
Spin correlations and Dzyaloshinskii-Moriya interaction in CsCuCl
M. A. Fayzullin, R. M. Eremina, M. V. Eremin +7
We report on electron spin resonance (ESR) studies of the spin relaxation in CsCuCl. The main source of the ESR linewidth at temperatures K is attributed to th…
