Abstract: The conditions of formation, the structure, and the stability of 0-degree domain walls with noncircular trajectories of the magnetization vector in cubic ferromagnets with induced uniaxial anisotropy along the [011] direction have been investigated. It has been found that magnetic inhomogeneities with such topology can appear only in an external magnetic field perpendicular to the domain wall plane. It has been shown that the Euler-Lagrange equations in the low-field limit can be reduced to second-order linear differential equations, whose solutions describe the structure of the above inhomogeneities, while the eigenvalues of the corresponding differential operators specify their stability conditions.
