Time-dependent micromagnetic structures in the domain wall merging, which plays an important role in the read operation of the Bloch line memory, have been studied precisely by solving the Gilbert equation. The modified Dufort-Frankel scheme for the 2nd order spatial differential was used to permit a practical time step. Simulation results indicated that the walls of an S=(1, 2, 0) stripe were merged more easily than those of an S=(1, 0, 0) stripe. It was found that wall merging begins near the film surfaces. The effect of in-plane magnetic fields on the wall merging process has also been studied.
