Bichurin, M.I.,Petrov, R.V.,Petrov, V.M.,Saplev, A.F.,Tatarenko, A.S.,Kovalenko, D.V.,Melnichuk, D.G.,Yang, Su-Chul Elsevier 2017 Materials research bulletin Vol.96 No.3
<P><B>Abstract</B></P> <P>The particular purpose of this paper is theoretical modeling of magnetoelectric interactions at the ferromagnetic resonance in a layered structure of a ferrite and a piezoelectric with through-thickness graded polarization. We show that using the functionally graded piezoelectric with through-thickness variation of polarization can lead to an electric field induced broadening of ferromagnetic resonance line. As an example, we consider the laminate based on the yttrium iron garnet layer which is placed between two lead zirconate titanate layers with different poling direction. The maximal ferromagnetic resonance line broadening of 9.3Oe is obtained for the yttrium iron garnet to lead zirconate titanate layer thickness ratio of 1.7 at 9.3GHz for E equal to 10kV/cm.</P> <P><B>Highlights</B></P> <P> <UL> <LI> Ferromagnetic resonance in a ferrite-piezoelectric laminate is studied. </LI> <LI> An electric field induced FMR line broadening results from bending the sample. </LI> <LI> Ferrite layer between the two piezoelectric layers shows a large line broadening. </LI> </UL> </P>
