Abstract: In DyPr–FeCo–B microwires with an easy magnetization axis directed along the microwire axis, domains with radial magnetization were found by the method of magneto-optical indicator films (MOIF). The width of the radial domains decreases with increasing field up to 30 mT, and increases with increasing diameter of the microwire in the range 60–105 $\mu$m. In wires of smaller diameter, the critical field for the appearance of radial domains is smaller. The influence of periodic scratches on the distribution of magnetization perpendicular to the microwire is found.
Keywords: domain structure, stray fields, microwires, rare earth magnets, magnetic domains, ferrimagnets.
