@article{Maeda2016QuasilocalizedIS, title={Quasi-localized Impurity State in Doped Topological Crystalline Insulator Sn0.9In0.1Te Probed by 125Te-NMR}, author={Satoki Maeda and Shotaro Katsube and Guo-qing Zheng}, journal={Journal of the Physical Society of Japan}, year={2016}, volume={86}, pages={024702} }

The In-doped topological crystalline insulator Sn1−xInxTe is a promising candidate for a topological superconductor, where it is theoretically suggested that In creates an impurity state responsible for superconductivity. We synthesized high purity Sn1−xInxTe samples and performed 125Te-nuclear magnetic resonance (NMR) measurements. The NMR spectra under a magnetic field of H0 = 5 T show a broadening characteristic due to a localized impurity state. The spin–lattice relaxation rate (1/T1…
