Control of magnetic and electric responses with electric and magnetic fields in magnetoelectric heterostructures

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.
