摘要：

Magnetostriction of amorphous ferromagnets with random local anisotropy and of polycrystalline ferromagnets originates both from a modification of the local magnetic anisotropy strength and from a strain-induced reorientation of the easy axes directions of the local structural units. The magnitudes of these two contributions to the magnetoelastic coupling energy and to the effective magnetostriction constant are calculated for materials with hexagonal local magnetic anisotropy.
