(Color online) Schematic illustrations of (a) the transformer/Terfenol-D laminate composites and the measurements with (b) 52-turn coil and (c) 20-turn coil. The later can collect the CME signal at different positions of Terfenol-D.
(Color online) Frequency dependence of the CME coefficient and phasic difference under 500 Oe measured with (a) 52-turn search coil and (b) 20-turn search coil at the position of maximal magnetic response.
(Color online) (a) CME coefficient as a function of the bias magnetic field and (b) induced magnetic flux density B ind as a function of input excitation voltage at half-wavelength and full-wavelength vibration modes with the different search coils.
(Color online) (a) CME distributions and (b) stress distributions calculated with Eqs. (1) and (2) in the magnetoelectric composite at half-wavelength and full-wavelength vibration modes under 500 Oe. The inset shows the scale for the CME distributional measurement.
(Color online) CME coefficient variation with the Terfenol-D thickness at half-wavelength and full-wavelength vibration modes measured with 20-turn coil.
