Abstract
The helicoid that forms in an external magnetic field in the presence of a point defect is modeled in the framework of the Landau theory of second-order phase transitions. A general solution to the nonlinear problem retaining all terms in the Helmholtz free-energy functional is obtained by means of Green functions. The magnetization distribution in the plane perpendicular to the helicoid axis and to the external field is calculated.
