Its thorough exploration as one of the best thermoelectric (TE) materials started in the 1950s [1]. Later, at the turn of the millennium, magnetic order induced by transition metals attracted much attention in the search for diluted magnetic semiconductors [2]. Its further rediscovery was related to nontrivial topology in electronic states at interfaces. The fact that it belongs to threedimensional (3D) topological insulators with one distinctive Dirac cone within the surface states triggered an enormous research effort [3,4]. This was accompanied by a wide variety of doping studies aimed at revealing the interference of magnetic/nonmagnetic impurities with topological surface states (TSS) in general. Within these studies, a couple of dopants proved to induce an unconventional (nematic) superconductivity (SC) [5–7].
