(2013). Structural dependence of nonlinear magnetoelectric effect for magnetic field detection by frequency modulation. Journal of Applied Physics, 114(14). doi: 10.1063/1.48243770021-8979http://hdl.handle.net/10919/52418The structure differences of magnetoelectric (ME) laminates for passive and active mode sensors are discussed. The Fourier coefficient A(1) calculated from the data of alpha(ME)-H-dc indicates that N = 1 (where N is the number of Metglas layers) should be the optimum structure for the active mode. Experimental investigations of the magnetic field sensitivity agree well with this conjecture. For N = 1, the magnetic field sensitivity was 0.66 nT/Hz(0.5), which was 3.1 times larger than for N = 5.
