An electrostatically tunable magnetoelectric inductor made of ring-type Pb(Zr, Ti)O-3(PZT)/MnZn ferrite/Pb(Zr, Ti)O-3(PZT) laminated composite has been developed. This tunable inductor worked in converse magnetoelectric effect, and with applying an electric field of 3 kV/ cm, it exhibited a large inductance tunability of up to 56.6% in a wide range of frequency. Such a large tunability in inductance was due to the strong electroelastomagnetic coupling between ferrite and piezoelectric layers. An analytical expression on the dependence of permeability mu(i) on applied electric field E was also developed, which predicted the measured results well. (C) 2010 American Institute of Physics.
