[en] Full text: There is considerable interest in understanding the fundamental physics in topological compounds that display exotic phenomena including metallic surfaces while the bulk is insulating. The most prominent representatives of three dimensional topological insulators are the binary systems Bi₂Se₃ and Bi₂Te₃. In 2016, we showed that the ⁷⁷Se nuclear magnetic resonance (NMR) in Bi₂Se₃ is governed by an exotic electronic spin susceptibility of Bloembergen-Rowland (BR) type giving rise to an unusually strong indirect dipole coupling among distant nuclei mediated by bulk electrons. In this report we present the results from 125Te NMR measurements from 7 T to 17.6 T on Bi₂Te₃ single crystals, micron sized powders, and nanopowders. The ¹²⁵Te results are the same as found by ⁷⁷Se NMR on Bi₂Se₃ where there are huge magnetic field independent NMR linewidths that are essentially doping independent (BR). A similar result is found for micron sized powders. But when grinding the material to very fine powders with dimensions on the 10’s on nm scale we find that the field independent linewidth increases dramatically, which has not been reported in the literature. Possible effects leading to this extraordinary observation will be discussed. (author)
