      Fabrication of a Novel Magnetic Topological Heterostructure and Temperature Evolution of its Massive Dirac Cone 

      Hirahara, T.; Otrokov, Mikhail M.; Sasaki, T. T.; Sumida, K.; Tomohiro, Y.; Kusaka, S.; Okuyama, Y.; Ichinokura, S.; Kobayashi, M.; Takeda, Y.; Amemiya, K.; Shirasawa, T.; Ideta, S.; Miyamoto, K.; Tanaka, K.; Kuroda, S.; Okuda, T.; Hono, K.; Eremeev, S. V.; Chulkov, Evgueni V. (Nature, 2020-09-24)
      Materials that possess nontrivial topology and magnetism is known to exhibit exotic quantum phenomena such as the quantum anomalous Hall effect. Here, we fabricate a novel magnetic topological heterostructure Mn4Bi2Te7/Bi2Te3 ...
