Effect of random anisotropy on magnetoelastic properties of amorphous ferromagnetic alloys

Random anisotropy model of magnetoelastic interaction is considered from both classical and quantum point of view. In both cases the exchange interaction is treated in the molecular field approximation. It was shown that the temperature dependence of the effective magnetoelastic tensor components has a complicated character, often different from the one predicted by the single-ion or two-ion theories.
