Resonant bending mode of Terfenol-D/steel/Pb(Zr,Ti)O3 magnetoelectric laminate composites

Resonant bending-mode Tb1-xDyxFe2-y/elastic-steel/Pb(Zr,Ti)O-3 magnetoelectric (ME) laminate composites have been investigated. An elastic-steel layer with a relatively high Q(m) significantly increases the resonant enhancement of the ME coefficient due to an increased effective Q(m) of the laminate. The three-phase ME laminates have a low first-order bending frequency of similar to 5 kHz, with a resonance-enhanced ME coefficient of similar to 40 V/cm Oe. (c) 2006 American Institute of Physics.
