Patent ID: 8536962

Claim:
Nanoswitch device comprising: at least one stationary element and at least one movable element which is at least partially made of a magnetic material and which is movable with respect to the stationary element, from a first position to a second position and from said second position to said first position said movable element being activated by: at least one first magnet 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 magnet 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, wherein the magnets are not in contact with each other, and at least one magnet comprises at least one antiferromagnetic material, at least one conductor, disposed in the at least one stationary element under the at least one first and second magnets, for heating, by flowing of a current in the conductor, the at least one antiferromagnetic material above the blocking temperature of said at least one magnet in order to inverse the direction of the remanent magnetization of said at least one magnet, no current flowing through said at least one magnet, said magnets configured to exert a magnetic interaction on said at least one movable element to move it from said first position to said second position and said magnets configured to exert a magnetic interaction on said at least one movable element to move it from said second position to said first position.
