Abstract
From zero-field-cooled and field-cooled magnetic response, we have determin ed the irreversibility lines for a number of high-T-c oxides, viz., La(Sr)- 214, Nd-223, Dy(Tb)-124, (Tl, Pb)-1212, and Tl-11112, in the H-T plane, whi ch fit the relation H = A(1 - T/T-c)(n). Our results are consistent with a correlation between the anisotropy of the structure and the value of n, is in agreement with the Josephson decoupling model [1].
