Charge-carrier behavior in Ba-, Sr- and Yb-filled CoSb3: NMR and transport studies
(2019)
We report 59Co NMR and transport measurements on n-type filled skutterudites BaxYbyCo4Sb12 and AxCo4Sb12 (A=Ba or Sr), promising thermoelectric materials. The results demonstrate consistently that a shallow defect level ...
Dirac electron behavior and NMR evidence for topological band inversion in ZrTe5
(2019)
We report 125Te NMR measurements of the topological quantum material ZrTe5. Spin-lattice relaxation results, well explained by a theoretical model of Dirac electron systems, reveal that the topological characteristic of ...
