Abstract: An experimental and theoretical study was carried out on the break-down of vertical-Bloch-line (VBL) chains in ordinary hard bubble walls subjected to an in-plane field, Hip. Other than a single critical value, a critical range of in-plane field, from H(1)ip to H(2)ip, was found. When Hip< H(1)ip the VBL chains keep unchanged; whereas when H(1)ip < Hip < H(2)ip, more and more hard domains are softened. Above H(2)ip all VBL chains are broken-down. A theoretical analysis showed that the critical range of Hip is originated from the serpentine curving of domain walls, and a relation H(2)ip / H(1)ip=√2, was obtained, which is in good agreement with the experiments.
