A 2π domain wall excitation is studied in a magnetic system. The domain walls studied before by other authors are different because in theses works the spin rotates by an angle of π in the domain wall. In 2π domain walls the spins rotate by an angle of 2π and the problem is described by a double sine‐Gordon equation, which has a richer dynamics than the conventional sine‐Gordon equation.
