domain wall

domain wall
a) An interface separating magnetic domains.

A domain wall corresponds to the rotation of the magnetization vector from one magnetic domain to another.

b) A two-dimensional singularity hypothesized in string theory.

The simplest soliton is the domain wall with co-dimension one, and the next simplest is the vortex with co-dimension two, whereas the co-dimension three (four) soliton is called monopole (instanton).
