Field and Polarization Dependent Quantum Spin Dynamics in Honeycomb Magnet NaCoTeO: Magnetic Excitations and Continuum
Patrick Pilch, Laur Peedu, Anup Kumar Bera +4
We report terahertz spectroscopic measurements of quantum spin dynamics in the spin-1/2 honeycomb magnet NaCoTeO as a function of applied magnetic field with different…
Spin-lattice and magnetoelectric couplings enhanced by orbital degrees of freedom in polar magnets
Vilmos Kocsis, Yusuke Tokunaga, Toomas Rõõm +5
Orbital degrees of freedom mediating an interaction between spin and lattice were predicted to raise strong magnetoelectric effect, i.e. realize an efficient coupling between magne…
Confinement of fractional excitations in a triangular lattice antiferromagnet
L. Facheris, S. D. Nabi, A. Glezer Moshe +6
High-resolution neutron and THz spectroscopies are used to study the magnetic excitation spectrum of CsCoBr, a distorted-triangular-lattice antiferromagnet with nearly XY-t…
Spin excitations in the magnetically ordered phases of MnScS
B. Tóth, K. Amelin, T. Rõõm +5
Recent neutron scattering experiments suggested that frustrated magnetic interactions give rise to antiferromagnetic spiral and fractional skyrmion lattice phases in MnScS.…
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…
Selection rules and dynamic magnetoelectric effect of the spin waves in multiferroic BiFeO
D. G. Farkas, D. Szaller, I. Kézsmárki +9
We report the magnetic field dependence of the THz absorption and non-reciprocal directional dichroism spectra of BiFeO measured on the three principal crystal cuts for fields…
