“…10 Figure 3 shows the measured variation of δH E for E = 8 kV/cm with the volume ratio for both in-plane and out-of-plane H. The field shift (and the ME constant A) decrease with increasing volume of YIG as predicted in our model. 10 Next we compare the ME constant for the single crystal bilayers with A for similar ferritepiezoelectric bulk and layered samples. For bulk YIG-PZT composites, the measured A = 0.33 Oe cm/kV is an order of magnitude smaller than current values for single crystal bilayers.…”

The first observation of microwave magnetoelectric (ME) interactions through ferromagnetic resonance (FMR) in bilayers of single crystal ferromagnetic-piezoelectric oxides and a theoretical model for the effect are presented. An electric field E produces a mechanical deformation in the piezoelectric phase, resulting in a shift δH E in the resonance field for the ferromagnet. The strength of ME coupling is obtained from data on δH E vs E. Studies were performed at 9.3 GHz on bilayers of (111) yttrium iron garnet (YIG) films and (001) lead magnesium niobatelead titanate (PMN-PT). The samples were positioned outside a TE 102 -reflection type cavity. Resonance profiles were obtained for E = 0-8 kV/cm for both in-plane and out-of-plane magnetic fields H. Important results are as follows. (i) The ME coupling in the bilayers is an order of magnitude stronger than in polycrystalline composites and is in the range 1-5.4 Oe cm/kOe, depending on the YIG film thickness. (ii) The coupling strength is dependent on the magnetic field orientation and is higher for out-of-plane H than for in-plane H. (iii) Estimated ME constant and its dependence on volume ratio for the two phases are in good agreement with the data.

“…In fact, FMR has been experimentally shown [15,16] to be sensitive to acoustic waves in ferromagnetic-ferroelectric structure. To our knowledge, multiferroic FMR, as suggested below has not yet been realized experimentally for the chosen interface, though several studies are known for multiferroic interfaces with other types of ME-coupling [17,18]. To be specific, we focus on a special class of ME coupled materials, so-called composite MFs [6,19], that may be synthesized from a wide range of materials that, when composed together yield a strong ME coupling and stable ferroelectric (FE) and ferromagnetic (FM) orders at room temperatures.…”

Understanding the multiferroic coupling is one of the key issues in the field of multiferroics. As shown here theoretically, the ferromagnetic resonance (FMR) renders possible an access to the magnetoelectric coupling coefficient in composite multiferroics. This we evidence by a detailed analysis and numerical calculations of FMR in an unstrained chain of BaTiO3 in the tetragonal phase in contact with Fe, including the effect of depolarizing field. The spectra of the absorbed power in FMR are found to be sensitive to the orientation of the interface electric polarization and to an applied static electric field. Here we propose a method for measuring the magnetoelectric coupling coefficient by means of FMR.

“…For instance, the phenomenological theory proposed recently to explain the ME effect at microwave frequency for laminate piezoelectric/magnetostrictive composites does not take into account of this dependence in a reasonable manner. 10 A recent research 11 on the magnetoelastic behaviors of Cu-Ni/Cu-Si epitaxial films sheds us a light on understanding the dependence mentioned earlier. It was revealed that the magnetostress coupling coefficient is a nonlinear function of the applied magnetic field and temperature.…”

The effect of dc magnetic bias field on the magnetoelectric coupling of a two-component magnetoelectric composite structure is investigated numerically using the finite-element method, in which the nonlinear magnetostress coupling for the magnetostrictive component is taken into account. It is shown that the magnetostress coupling coefficient increases first and then falls down with increasing of the bias field, and this behavior is argued to be responsible for the dependence of magnetoelectric yield on the bias field. The numerical modeling using the ANSYS5.5 finite element algorithm for the Tb0.3Dy0.7Fe1.9-epoxy/Pb(Zr0.52Ti0.48)O3-epoxy composite structure gives fairly consistent results with the experiments.
