ABSTRACT:
The magnetic device according to the invention is integrated on a substrate and comprises at least one element made of piezoelectric material associated with actuating electrodes, and at least one magnetic element able to deform under the stress of the piezoelectric material element. The device has the form of a beam movable with respect to the substrate, and comprises two transverse parts of predetermined width, along a reference longitudinal axis. The piezoelectric material element is formed by at least a part of a transverse part and each transverse part comprises a zone for mechanical anchoring on the substrate. The transverse parts are connected by at least one central branch, of predetermined width, on which the magnetic element is arranged.
