a Zero bias dI/dV mapping of a vortex at 0.1 T with the spin non-polarized tip on the topological superconductor 5 QL Bi2Te3/NbSe2. b dI/dV at the vortex center measured with a fully spin polarized tip. Red curves are for parallel configuration and black curves are for antiparallel configuration. The blue lateral lines give the average values of the intensities in multi-measurements, the vertical bars are the standard error bars. c dI/dV at 10 nm away from the center of a vortex measured with a fully spin polarized tip, where the tunneling is found independent of the spin polarization. d and e Theoretical calculation of the dI/dV curves in two configurations and the experimental results accordingly. a–e reprinted with permission from ref. 48, copyright 2016 by the American Physical Society
