Considered the excitation of nonlinear forced oscillations of magnetization and elastic displacement in a normally magnetized ferrite plate having magnetoelastic properties. The problem is solved on the basis of a simplified model system of two coupled oscillators, one of which has gyromagnetic properties. It is shown that in conditions of multiplying the frequency of the second oscillator relative to the frequency of the first, a negative and large enough value of the parameter when the nonlinear excitation of oscillations is delayed in time. For the interpretation of time lag effect of the proposed hypothesis along with the additional minimum of the potential of the system, separated from the main by a potential barrier.
