Flux distraction effect on magnetoelectric laminate sensors and gradiometer
A magnetic flux distraction effect caused by a nearby metallic material was investigated for Metglas/Pb(Mg1/3Nb2/3)O-3-PbTiO3 laminated magnetoelectric ( ME) sensors. Using flux distraction, a ME sensor can perform an accurate search for metallic targets of different dimensions at various distances. Detection results and simulations were in good agreement. The findings demonstrate an effective means to employ stationary ME sensors and gradiometers for magnetic search applications. (C) 2013 AIP Publishing LLC.
