Abstract:
From the hystereses in DC magnetization loops, we determined critical current densities J c and irreversibility fields B irr of high temperature superconductors Sr 2 Ca 2 Cu 3 O 7+δ (0223) and Sr 2 Ca n -1 Cu n O 2 n +δ F 2+ y (02( n -1) n - F, n =2, 3) prepared under high pressure. These phases have simple, thin blocking layers consisting of double SrO–SrO or SrF–SrF planes without any cations between them. J c and B irr of 0223 were larger than those of 0223-F, which seems to reflect the difference in the O-based and F-based blocking layers. The J c and B irr values obtained for the three phases were comparable to or even smaller than those of Hg-1223 and (Bi, Pb)-2223, in spite of their small spacings between the CuO 2 multilayers.
