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 exceeds on the multiple part of resonance frequency of magnetic system,
in strong nonlinear regime of excitation it is possible the multiplication 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 multiplication and supposed some
hypotheses of its interpretation.
Key words: magnetostriction transducer, nonlinear vibrations,
multiplication of frequency.
