✦ Synopsis

The structures of n soliton in superfluid 3He-B phase in slab geometry are studied. In the geometry, there are four degenerate equilibrium directions of the n vector, which allows the n soliton (domain wall) separating two domains with different directions of n. We get the structure of the soliton by minimizing its total free energy and find that the bending energy of n changes symmetry of the soliton. The result is compared with the NMR data obtained by Ishikawa et al.
