(2010). High magnetic field sensitivity in Pb(Zr,Ti)O(3)-Pb(Mg(1/3)Nb(2/3))O(3) single crystal/Terfenol-D/Metglas magnetoelectric laminate composites. Journal of Applied Physics, 107(9). doi: 10.1063/1.34061420021-8979http://hdl.handle.net/10919/52453We report the magnetic field sensitivity results on five layer structure given as Metglas/Terfenol-D/PMN-PZT/Terfenol-D/Metglas, where PMN and PZT correspond to Pb(Mg(1/3)Nb(2/3))O(3) and Pb(Zr,Ti)O(3), respectively. The piezoelectric constant (d(33)) of poled PMN-PZT was found to be 1600 pC/N with dielectric constant of 5380 at 1 kHz. The sensitivity measurements were conducted after attaching individual layers in the laminate clearly delineating the effect occurring in the response. The magnetoelectric response for this five layer structure at 1 kHz was found to be 5 V/cm Oe at dc bias field of 1000 Oe under an ac drive of 1 Oe. At 1 kHz frequency, the sensor was able to deterministically measure step changes of 500 nT while at 10 Hz we can clearly identify the sensitivity of 1 mu T. These results are very promising for the cheap room-temperature magnetic field sensing technology. (C) 2010 American Institute of Physics.
