Abstract :
Magnetic properties of high quality Bi and Bi1−x–Sbx ( x ≤ 0.07 ) bicrystals of inclination type were studied in the temperature range (1.8–30) K using a quantum design SQUID magnetometer. It is found that the crystallite interfaces of some of these bicrystals show clear evidence for a superconducting transition at much higher critical temperatures ( ∼ 21 K) than other Bi nanoobjects.
