Based on the experimental data of the magnetic hysteresis and magneto-optical images of the magnetic structure during magnetization process, in this work, we have carried out estimation of the value of radial mechanical stresses in the surface region of the metal core of microwire. The composition of the sample microwire was Fe73.9B13.2Si10.9C2 with a positive magnetostriction constant. The magneto-optical images of the domain structure during magnetization and the hysteresis loops have been used to define the magnetic characteristics of the sample (the saturation magnetization Ms and the saturation field Hs). We have determined that there is a relationship between the orientation of the magnetic moments of the ring-shaped surface domains and the internal cylindrical domains. On the basis of the experimental data, we have estimated the value of radial mechanical stress of the microwire in the surface region of the metal core where the ring-shaped domains are located.
