Nonlinear magnetoelectric response of a Metglas/piezofiber laminate to a high-frequency bipolar AC magnetic field
Abstract
A nonlinear magnetoelectric (ME) response has been investigated in a Metglas/piezofiber laminate by applying a bipolar AC magnetic field (Hac) without a DC magnetic bias. The ME voltage (VME) was measured for various amplitudes of Hac of up to 9 Oe over the frequency (f) range 0.1 < f < 40 kHz. Compared to the linear ME behavior, an anomalous response to f and Hac was observed, which is believed to be associated with the Eddy-current loss in the Metglas layers. A frequency multiplication effect was also observed for VME, which was understood by Fourier analysis of the nonlinearity in the magnetostriction.
