Growth of bulk crystals of magnetic topological insulators under peritectic conditions
Anton I. Sergeev, Alexander S. Frolov, Nadezhda V. Vladimirova +9
Magnetic topological materials (MTIs) including MnBiTe are of scientific interest due to the possibility to reveal the interplay between topological and magnetic orders. Fo…
Interfacing Quantum Spin Hall and Quantum Anomalous Hall insulators: Bi bilayer on MnBiTe-family materials
I. I. Klimovskikh, S. V. Eremeev, D. A. Estyunin +17
Meeting of non-trivial topology with magnetism results in novel phases of matter, such as Quantum Anomalous Hall (QAH) or axion insulator phases. Even more exotic states with high…
