Abstract
The paper gives a description of hypersound magnetoelastic oscillations excitation along magnetisation reversal of normal magnetized single-layer and multi-layers ferrite plates, also provides definition of distinctive features of magnetic and elastic oscillations development. The relation of oscillations to the parameters of saturation magnetization, magnetic and elastic damping has been revealed.

The problem is solved in a Cartesian coordinate system Oxyz
Summary
The magnetoelastic oscillations generation caused by magnetisation reversal is one of the interesting interaction mechanism of magnetic, elastic and magnetoelastic subsystems. This process can be executed in case of action on the plate by alternating magnetic field, hypersound oscillations as well as pulsed magnetisation reversal in a DC field. Dimensions and shape of a plate are fitted in such a way that avoid chance of uniform precession parametric decay into exchange spin wave [1]
