magnetic shape memory alloys,
MSM shape memory alloys,
The Magnetic Shape Memory (MSM) eàect in a Ni-Mn-Ga alloy was discovered in 1996 at MIT by Dr. Kari Ullakko and co-workers
The first MSM alloy showed a strain of 0.2%. Since then, huge improvements have been achieved in the production process
of MSM alloys as well as in the post-production treatments and training.
MSM alloys are ferromagnetic materials that produce motion and force under moderate magnetic fields (typically higher than 0.2 T). They are single crystalline alloys of Nickel, Manganese and Gallium and are able to produce 6% strain under more than 2 MPa external load (see Fig. 3). Frequencies up to lower kilohertz range can be achieved.
The main properties of commercially available Ni50-Mn28-Ga22 alloys are:
