Аннотация
The values of internal stresses σi that determine the maximum of the dependence of differential permeability μd (H) have been obtained as well as the limiting value of the angle between highand low-angle grain boundaries. When analyzing 90-degree transitions, singular points have been discovered that separate domains with different values of critical magnetization-reversal fields. This has made it possible to calculate the values of all magnetizations, including easy-plane (EP), residual, and “reverse” ones (in the area of positive magnetic-field values). The results open up possibilities for conscious choice of the field ranges for excitation of irreversible 90-degree transitions with known values of σi. The latter can serve as the basis for developing new techniques of nondestructive testing.
