Giant magnetostriction of exchange-coupled (TbFe/Fe) ML with high sensitivity after heat treatment

Résumé

The possibility to improve the magnetoelastic (ME) properties of exchange-coupled (TbFe/Fe) multilayers (ML) after post-deposition annealing treatment is presented. Giant magnetostriction (GMS) improvement has been observed in highly anisotropic single domain state (SDS) multilayers deposited by ion sputtering under a magnetic polarization field H/sub d/ from two points of views corresponding to strong increase of both the magnetoelastic constant b/sup /spl gamma/,2/ by about 75% and the GMS sensitivity db/sub f//dH, by a factor 6 (b/sub f/ is the ME parameter of the flexural motion of the (TbFe/Fe)/spl times/40/glass bimorph). These improvements have been induced for both the flexion and the torsion motions of the bimorphs submitted to either a static or a dynamical magnetic field which can excite linear and nonlinear anharmonic oscillating modes.
