The magnetization in the domain walls (DWs) formed inside the inner core of the amorphous ferromagnetic microwire is studied within a simple analytical model proposed. The influence of the ordering in the internal-stress created outer shell of the wire is included via an effective Dzyaloshinskii-Moriya-like anisotropy and resulting DW textures have been classified. The model is applicable to periodically constricted nanowires (whose core-shell magnetic structure follows from the magnetostatics) as well, which has enabled the verification of the predictions on DW structure with the micromagnetic simulations.
