Refining magnetic interactions from the magnetic field dependence of spin-wave excitations in magnetoelectric LiFePO
L. Peedu, V. Kocsis, D. Szaller +13
We investigated the spin excitations of magnetoelectric by THz absorption spectroscopy in magnetic fields up to 33T. By studying their selection rules, we fou…
Investigation of the magnetoelastic coupling anisotropy in the Kitaev material -RuCl
Vilmos Kocsis, David A. S. Kaib, Kira Riedl +9
The Kitaev material -RuCl is among the most prominent candidates to host a quantum spin-liquid state endowed with fractionalized excitations. Recent experimental and theoret…
Switching of antiferromagnetic states in LiCoPO as investigated via the magnetoelectric effect
Vilmos Kocsis, Yusuke Tokunaga, Yoshinori Tokura +1
The linear magnetoelectric (ME) effect allows for the selection or switching between two antiferromagnetic (AFM) states via the application of large electric () and magnetic ($H…
Berry curvature generation detected by Nernst responses in ferroelectric Weyl semimetal
Cheng-Long Zhang, Tian Liang, M. S. Bahramy +6
The quest for nonmagnetic Weyl semimetals with high tunability of phase has remained a demanding challenge. As the symmetry breaking control parameter, the ferroelectric order can…
Magnetoelectric spectroscopy of spin excitations in LiCoPO4
Vilmos Kocsis, Sándor Bordács, Yusuke Tokunaga +7
We have studied spin excitations in a single-domain crystal of antiferromagnetic LiCoPO4 by THz absorption spectroscopy. By analyzing the selection rules and comparing the strength…
Strong magneto-optical effects in ACr2O4 A=Fe, Co spinel oxides generated by tetrahedrally coordinated transition metal ions
Vilmos Kocsis, Sándor Bordács, Joachim Deisenhofer +5
Magneto-optical effects have been investigated over the infrared{visible spectral range in ACr2O4 (A = Fe, Co) spinel oxides with non-collinear spin orders in their ground states.…
