Acoustic microscope based on magneto-elastic wave phase conjugator

Andrey Brysev, Leonid Krutyansky, Philippe Pernod, Vladimir Preobrazhensky

Acoustic C-scan imaging (acoustic microscopy) by means of supercritical parametric wave phase conjugation (WPC) is studied experimentally. A phase conjugator based on a magneto-acoustic active material is used for compensating phase distortions introduced by solid and polymer aberration layers…

Giant magnetostriction thin films for multi-cantilever micro-structures driving

Nicolas Tiercelin, Philippe Pernod, Vladimir Preobrazhensky, Henri Le Gall, Jamal Ben Youssef, Patrick Mounaix, Didier Lippens

First results on the realisation of a micrometer GaInAs multi-cantilever structure (50×30×1 μm3 each) driven by amorphous TbFe magnetostrictive thin films are presented. Magneto-elastic properties of the cantilevers were studied by dynamic excitation methods. A resonance of the bimorph cantilevers…

Giant magnetostriction (GMS) of TbFe monolayer with improved field-induced anisotropy and sensitivity

Henri Le Gall, Jamal Ben Youssef, J. Ostorero, Nicolas Tiercelin, Philippe Pernod, Vladimir Preobrazhensky

Giant magnetostriction, (GMS), reported until now in thin films using rare earth-transition metal RM/sub 2/ (R=Tb, Sm, and M=Fe, Co) compounds, presents in most cases an isotropic or quasi-isotropic magnetoelastic (ME) behavior. A large change of the ME coefficient b under the lowest possible…
