Transport measurements have been made on Bi2Sr2CaCu2O8 single crystals in both Corbino disc and strip geometries. Pronounced differences are observed in both the resistive transition and the current-voltage characteristics in these two geometries. Su

Magnetic moment measurements have been made on differently shaped single crystals of Bi 2 Sr 2 CaCu 2 O 8+ δ using a SQUID magnetometer. In platelet shaped samples, the results show a pronounced geometrical barrier (GB) or `shape effect' at low fiel

International audience; Transport and local magnetization measurements carried out simultaneously in Bi2Sr2CaCu2O8 (BSCCO) crystals reveal finite resistivity well below the magnetic irreversibility line, where the vortices should be pinned. This resi
