Abstract: We study theoretically the structure of domain walls in ferromagnetic stateson Mobius strips. A two-dimensional classical Heisenberg ferromagnet withsingle-site anisotropy is treated within a mean-field approximation by takinginto account the boundary condition to realize the Mobius geometry. It is foundthat two types of domain walls can be formed, namely, parallel or perpendicularto the circumference, and that the relative stability of these domain walls issensitive to the change in temperature and an applied magnetic field. Themagnetization has a discontinuity as a function of temperature and the externalfield.
