Spin-Chiral Bulk Fermi Surfaces of BiTeI Proven by Quantum Oscillations
Joonbum Park, E. Kampert, Kyung-Hwan Jin +10
We present the Fermi-surface map of the spin-chiral bulk states for the non-centrosymmetric semiconductor BiTeI using de Haas-van Alphen and Shubnikov-de Haas oscillations. We iden…
Anisotropic Dirac fermions in a Bi square net of SrMnBi2
Joonbum Park, G. Lee, F. Wolff-Fabris +8
We report the highly anisotropic Dirac fermions in a Bi square net of SrMnBi2, based on a first principle calculation, angle resolved photoemission spectroscopy, and quantum oscill…
Magnetoelectric effects in an organo-metallic quantum magnet
V. S. Zapf, F. Nasreen, F. Wolff-Fabris +1
We observe a bilinear magnetic field-induced electric polarization of 50 in single crystals of NiCl-4SC(NH) (DTN). DTN forms a tetragonal structure that breaks…
Magnetically-induced electric polarization in an organo-metallic magnet
V. S. Zapf, M. Kenzelmann, F. Wolff-Fabris +2
The coupling between magnetic order and ferroelectricity has been under intense investigation in a wide range of transition-metal oxides. The strongest coupling is obtained in so-c…
