Near-infrared magnetic linear and non-reciprocal directional dichroism in the chiral antiferromagnet SmFe3(BO3)4
B. Beke, B. Szász, I. A. Gudim +2
We investigated the influence of antiferromagnetic (AFM) order on the near-infrared optical re- sponse of SmFe3(BO3)4 by polarization-resolved, magneto-optical spectroscopy. Below…
Nodal line resonance generating the giant anomalous Hall effect of CoSnS
F. Schilberth, M. -C. Jiang, S. Minami +11
Giant anomalous Hall effect (AHE) and magneto-optical activity can emerge in magnets with topologically non-trivial degeneracies. However, identifying the specific band structure f…
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…
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.…
