Abstract The magnetic properties of bicrystals and tricrystals of Bi 1− x –Sb x ( x ≤ 0.2) alloys were studied in a temperature range of 1.8–100 K. The ferromagnetic‐like hysteresis loops are found in tricrystals and some bicrystals. We revealed that nano‐width crystallite interfaces (∼100 nm) exhibit superconducting behavior, whereas the single crystalline samples are not superconducting. The onset of superconducting transition (∼36 K) in some of these interfaces considerably exceeds the values of other semimetal nanoobjects.
