Journal of Applied Physics, 111(10). doi: 10.1063/1.47184410021-8979http://hdl.handle.net/10919/52420We have investigated the equivalent magnetic noise and magnetic field sensitivity for a magnetoelectric (ME) sensor unit of N numbers of ME laminates stacked together. Our results show with increasing N that the modeled and measured equivalent magnetic noises decreased by a factor of root N and that the magnetic field sensitivities increased by root N. For Metglas/Pb(Mg-1/3,Nb-2/3) O-3-PbTiO3 laminates, the equivalent magnetic noise decreased and the magnetic field sensitivity increased by a factors of 2.1 and 2.3, respectively, for N = 4 relative to that for N = 1.
