Multiplicative Frequency Conversion in a Scheme of Magnetostrictive Transducer. Frequency Multiplication in the Relaxation Regime

Resumo

Stimulated oscillations of magnetization and elastic displacement in a normally magnetized ferrite plate with magnetoelastic properties are considered. Frequency multiplication at the ratio determined by the multiplicity of the resonance frequencies of the magnetic and elastic subsystems is analyzed. Time and amplitude characteristics of the effect are studied using a model of the impact excitation of the elastic system due to short-term effect of the magnetic system. Frequency division in the same scheme of the magnetostrictive transducer is employed for comparison.
