摘要：
Measurements of the intermediate superconducting transitions seen in AC susceptibility measurements of directionally solidified ''single crystals'' of YBCO have been made for the fields parallel and perpendicular to the c-axis. The results show a high degree of correlation between the different directions, and these have been interpreted in terms of the screening-current loops associated with each orientation. The amplitude dependence of the peak positions for AC magnetic fields in the range 70-350 mOe follow the general rule h0 = beta((T(i)-T(m))/T(i))1.
