Abstract

Micromagnetic equilibrium conditions are derived for ferromagnets of amorphous lattice structure. The effect of fluctuations of the spontaneous magnetization as well as of “inhomomogeneitie” of the amorphous state which give rise to internal stresses is discussed within the framework of a semi-classical micromagnetic theory. It is shown that the microstructural contribution, A/H ext , to the high-field magnetization results from the magnetostrictive interaction between the spontaneous magnetization and straight dislocation dipoles of a density N D ≈ 10 13 /cm 2
