Title: Experimental magnetization evidence for two superconducting phases in Bi bicrystals with large crystallite disorientation angles

Abstract

Magnetization measurements prove that the magnetic properties of large-angle ({theta}>30 deg. ) bismuth bicrystals with a crystallite interface (CI) of twisting types essentially differ from well-known results on single-crystalline specimens. Two superconducting phases with T{sub c}{approx}8.4 K and {approx}4.3 K were observed at the CI of bicrystals while ordinary rhombohedral Bi is not a superconductor. We conclude that these phases have to do with the central part and the adjacent layers of the CI of bicrystals.
