Abstract

The amplitude-independent component of magnetic losses (the internal friction) and the dynamic defect of Young's modulus associated with processes of reversible displacements of domain walls and rotations of spontaneous magnetization vectors are described theoretically for idealized triaxial magnets considering the actual domain structure, the domain wall type, and the concentrations of magnetic phases. From formulas obtained by the perturbation method it follows that the contribution of rotation processes to the effects examined is rather noticeable.
