    Control of magnetic and electric responses with electric and magnetic fields in magnetoelectric heterostructures
    Das, J.; Li, M.; Kalarickal, S. S.; Altmannshofer, S.; Buchanan, K. S.; Li, Jiefang; Viehland, Dwight D. (AIP Publishing, 2010-05-01)
    This paper reports on the tuning of both magnetic and electric responses with electric and magnetic fields for metglas-Pb(Zr,Ti)O(3) based magnetoelectric (ME) heterostructures that can be promising for communication and sensor applications. The hysteresis loop results indicate a change in the in-plane magnetization due to application of voltages that leads to a tuning of the ferromagnetic resonance frequency by up to about 210 MHz with electric field. Furthermore, these structures show a high ME voltage coefficient that results in the detection of a 2 nT ac magnetic field and a low noise floor. (C) 2010 American Institute of Physics.

    Enhancement in the field sensitivity of magnetoelectric laminate heterostructures
    Das, J.; Gao, J.; Xing, Zengping; Li, Jiefang; Viehland, Dwight D. (AIP Publishing, 2009-08-01)
    The effect of magnetostrictive layer thickness on the magnetoelectric (ME) response and field sensitivity of Pb(Zr,Ti)O(3)-metglas based sandwiched ME heterostructures has been studied. Such structures hold promise for sensor applications. The increase in metglas thickness results in a significant increase in the ME response and magnetic field sensitivity. The ME coefficient and field sensitivity increase by about 1.5-1.75 and 2.7 times, respectively, for a structure with 150 mu m thick six metglas layers on both sides of the Pb(Zr, Ti)O(3), in comparison to a 50 mu m thick two layered structure.
