An international team of researchers (USA – University of Chicago, Pennsylvania State University, Israel) discovered a new material, MnBi6Te10, which could be used to create quantum highways useful in connecting the internal components of energy-efficient quantum computers. In the ferromagnetic phase, an energy gap of 15 meV was resolved at the Dirac point on the MnBi2Te4 termination. In contrast, antiferromagnetic MnBi6Te10 exhibited gapless topological surface states on all terminations. Measurements revealed substantial Mn vacancies and Mn migration in ferromagnetic MnBi6Te10. They provided a conceptual framework where a cooperative interplay of these defects drove a delicate change of overall magnetic ground state energies and led to tunable magnetic topological orders. According to the researchers their work provided a clear pathway for nanoscale defect-engineering toward the realization of topological quantum phases…read more. Open Access TECHNICAL ARTICLE
