| Rezumat | |
The weak magnetism, superconductivity, and quantum oscillations phenomena in Bi1xSbx (0 ≤ x ≤ 0.2) crystallite structures with nano-width multilayer interfaces have been studied. We found that the Dirac charge carriers in interface layers are much heavier than in the bulk crystallites, the high imperfection at interfaces has a significant influence on carrier scattering, which predetermines the manifestation of various anomalies of electronic magneto-transport. One or two superconducting transitions with Tc ≤ 21 K were detected in all structures, some of them also showed weak ferromagnetism, while others with a rather high content of imperfections and two superconducting transitions exhibit dual superimposed ferromagnetic and superconducting hysteresis loops, indicating simultaneously coexistence of superconductivity and weak ferromagnetism. |
