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.
