Evaluation of magnetomechanical conversion efficiencies in magnetoelectric gyrators
Source abstract
Abstract
Magnetomechanical conversion abilities of several Nickel, Metglas and Terfenol-D were investigated by using a constructed magnetic power path with two winding coils. We characterized the magnetostriction efficiency as a function of power density with the optimal load resistor and magnetic bias. We found a high magnetomechanical conversion efficiency of 95% and 90% under low power drive for a Metglas layer and a Metglas/Pb(ZrXTi1-X)O3 composite, respectively.
