The structure of domain walls in cylindrical nano- and microwires with a non-uniform anisotropy distribution in the transverse-radial direction has been studied. This distribution can be controlled by mechanical stresses associated with specific wire manufacturing methods as well as with the glass coating in some types of microwires. Our calculations have shown that in the presence of axial anisotropy in the core of the wire and radial anisotropy near its surface, various configurations of domain walls can be stabilized. A diagram of magnetic states has been calculated depending on the radial anisotropy values. The stability of various types of domain walls and their possible transformation under the excitation of thermal fluctuations and external perturbations are discussed.
Keywords: cylindrical systems, amorphous ferromagnetic microwires, mechanical stress, micromagnetics.
