Аннотация

—Hypersonic elastic oscillations are excited in the microwave range using magnetization reversal of a normally magnetized ferrite plate due to precession of the magnetization vector around the field direction. Characteristic times are determined for magnetic and elastic oscillations, and the relation of these times with decay parameters of both processes are demonstrated. An empirical analysis using exponential functions and a model of the quasistatic rotation of the magnetization vector are employed for interpretation of the effects. Prospects for application of the effects for the excitation of highpower microwave hypersound are discussed, and a possibility of elastic oscillations with amplitudes of up to 10–9 cm is demonstrated.
