We hereby present a solution for self biasing of magnetic films using micropatterned permanent magnets. Micromagnetic simulations were used as a designing and optimization tool to create a biasing structure. Samples were elaborated with varying geometric parameters using classical silicon microfabrication techniques. Nanostructured TbCo/FeCo magnetostrictive thin films were sputtered over coercive FePt filled trenches etched in silicon. Magnetic and magnetoelastic characterizations confirmed numerical simulations. In particular, non-linear actuation of a self-biased magnetostrictive cantilever has been obtained at zero external polarizing field.Lire moins >
