Abstract
A nanoswitch device comprising: at least one stationary element (52) and at least one element (50) which is at least partially made of a magnetic material and which is movable with respect to the stationary element, means of activating the movable element, comprising: and at least one first and one second magnetic means (30, 30′, 40, 40′) each having a planar shape, defining a first and a second plane, in order to generate remanent magnetization in a direction contained within said first plane or perpendicular to this first plane, means (36, 36′) for reversing the direction of the remanent magnetization of at least one of said first and second magnetic means.

Nanoswitch device comprising:
- at least one stationary element and at least one element which is at least partially made of a magnetic material and which is movable with respect to the stationary element,
- means of activating the movable element, comprising:
- at least one first magnetic means having a planar shape, defining a first plane, in order to generate remanent magnetization in a direction contained within said first plane or perpendicular to this first plane,
- and at least one second magnetic means having a planar shape, defining a second plane, in order to generate remanent magnetization in a direction contained within said second plane or perpendicular to this second plane,
- means for reversing, by a thermal effect, the direction of the remanent magnetization of at least one of said first and second magnetic means.
