Successive incommensurate spin orderings and excitations in multiferroic SrMnGe2O6
Claire V. Colin, Lei Ding, Eric Ressouche +8
Anisotropic multiferroic properties of SrMnGe2O6 pyroxene single crystals were systematically investigated by means of magnetization, heat capacity, pyroelectric current measuremen…
Crystal and magnetic structures of magnetic topological insulators MnBiTe and MnBiTe
Lei Ding, Chaowei Hu, Feng Ye +3
Using single crystal neutron diffraction, we present a systematic investigation of the crystal structure and magnetism of van der Waals topological insulators MnBiTe and Mn…
Giant spontaneous exchange bias in an antiperovskite structure driven by a canted triangular magnetic structure
Lei Ding, Lihua Chu, Pascal Manuel +4
Exchange bias (EB) refers to a shift of the hysteresis loop along the field axis in materials consisting of ferromagnetic (FM) and antiferromagnetic (AFM) layers, generally after a…
Colossal magnetoresistance in the insulating ferromagnetic double perovskites TlNiMnO: A neutron diffraction study
Lei Ding, Dmitry D. Khalyavin, Pascal Manuel +4
In the family of double perovskites, colossal magnetoresistance (CMR) has been so far observed only in half-metallic ferrimagnets such as the known case SrFeMoO where it ha…
A van der Waals antiferromagnetic topological insulator with weak interlayer magnetic coupling
Chaowei Hu, Xiaoqing Zhou, Pengfei Liu +11
Magnetic topological insulators (TI) provide an important material platform to explore quantum phenomena such as quantized anomalous Hall (QAH) effect and Majorana modes, etc. Thei…
Gapless spin-liquid state in the structurally disorder-free triangular antiferromagnet NaYbO
Lei Ding, Pascal Manuel, Sebastian Bachus +8
We present the structural characterization and low-temperature magnetism of the triangular-lattice delafossite NaYbO. Synchrotron x-ray diffraction and neutron scattering exclu…
