Abstract

Magnetic and magnetotransport properties were studied on Bi_2.2Sr₂Ca_0.8Cu₂O_8+δ single crystals. The normal state resistivity in the a-b plane varies linearly with temperature and extrapolates to zero at T = 0. The slopes of the upper critical field are −4.5+1(−0.55) T/K for H perpendicular (parallel) to the c-axis. The coherence length is calculated to be ≈30A˚in the a-b plane but only ≈A˚perpendicular to it. ξ_c is thus shorter than the 12A˚spacing between the Cu-O double layers. From H_c1 and H_c2 data, the Sommerfeld parameter γ is deduced.
