Abstract
Magnetoelectric (ME) response of a multilayer ferrite-piezoelectric structure to short magnetic field pulses has been measured. The frequency spectrum of the ME coefficient αE of the structure in the range from several dozen hertz to 1 MHz has been determined by Fourier analysis of the ME response signal. The αE value shows a general slow monotonic decrease with increasing frequency and exhibits a 7-to 30-fold reso-nance growth at certain frequencies, which is related to the excitation of intrinsic acoustic oscillations of the multilayer structure. In the low-frequency range, the ME coefficient has a maximum in the region of 1 kHz due to relaxation processes in the piezoelectric and ferrite layers.
