Abstract. The forced vibrations of
magnetization and elastic displacement in normal magnetized ferrite plate
having magnetoelastic properties are investigated. In the case when resonance
frequency of elastic system is equal to the multiple part of resonance
frequency of magnetic system, in strong nonlinear regime of excitation it is
possible the division of initial frequency in whole-number and also in
fractional-number relation. It is investigated the cases of circular and linear
polarization of excitation field. It is found the different regimes of division
and supposed some hypotheses of its interpretation.
Key words: magnetostriction
transducer, nonlinear vibrations, division of frequency.
