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.
