Abstract

DC magnetic measurements on the high-T_c superconductors YBa₂Cu₄O₈ (124, T_c=80 K) and Y_0.9Ca_0.1Ba₂Cu₄O₈ (T_c=87K) are reported. The irreversible lines of 124 and ceramic YBa₂Cu₃O₇ (123) are quite similar. The results show that there is no significant difference between the critical currents of the 124 phase and those of the 123 phase. Conversions of 124 into 123+CuO does not change the grain size of the material but enhances its critical current density.
