Abstract
In the first-order anharmonicity approximation of Hooke's law, the amplitudes of elastic waves, absorption coefficients, wave numbers of the fundamental wave and of the first harmonic generated by an alternating magnetic field with a preset orientation relative to the basis axes of a crystal having arbitrary dimensions are calculated for multidomain magnets with rigidly fixed domain boundaries in terms of concentrations of magnet phases and magnetic structure parameters with allowance for the wave equation and angular momenta.
