Phys. Lett. 102, 102905 (2013); http://dx.doi.org/10.1063/1.47953070003-6951http://hdl.handle.net/10919/24947A nonlinear magnetoelectric (ME) response has been investigated in a Metglas/piezofiber laminate by applying a bipolar AC magnetic field (H-ac) without a DC magnetic bias. The ME voltage (V-ME) was measured for various amplitudes of H-ac 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 H-ac 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 V-ME, which was understood by Fourier analysis of the nonlinearity in the magnetostriction. (C) 2013 American Institute of Physics.
