Magnetoelastic waves in multilayered structures — •Zukhra Gareyeva — IMCP,prospect Octyabrya 151, Ufa , Russia

The presented paper reports investigation of dynamic properties of magnetoelastic and elastic waves in confined layered structure representing a system made of magnetostrictive thin films deposited on nonmagnetic substrates. Application area of such structures is wide and encounters sensors and actuators for bulk and microelectromechanical devices, devices for delay lines, angular motion, torque generation, magnetic labels etc. In this article we draw attention to frequencies of vibrations induced by variable magnetic field in composed films-substrate system and peculiarities of their behavior under the change of intrinsic and external parameters. We show dispersion law of composite system differs from the case of thin magnetic film. It reveals in peculiarities of dimensional resonant frequencies behaviour. Results of investigation are expected to be important both from theoretical and practical point of views: to predict behaviour of magnetostrictive systems subjected to magnetic dynamic loads, to determine elastic and magnetoelastic properties of materials from dynamic experiments, to control dimensional resonances frequencies in composite oscillator devices, to contribute to the laminated plate theory.
