The lower critical fields (H_c1) of Bi₂Sr₂CaCuO_8+d and YBa₂Cu₃O_7-d single crystals were measured by SQUID at various temperatures below T_c. The measurements were based on studies of type-II superconductors in the framework of the modified Kim-Anderson model. Results show that H_c1,c(T) (H∥c axis) and H_c1,ab(T) (H⊥c axis) for BSCCO show an anomalous upturn below about 40 K, but those for YBCO do not show any anomaly.
