Development of Microactuators Based on the Magnetic Shape Memory Effect (Schriften des Instituts fuer Mikrostrukturtechnik am Karlsruher Institut fuer ... fuer Mikrostrukturtechnik) (Volume 21)

The giant magneto-strain effect in Ni-Mn-Ga alloys is particularly attractive for actuator applications. Two different approaches are being pursued to develop MSM microactuators. To observe large deflections of Ni-Mn-Ga microactuators, the material should be exhibiting low twinning stress and large magnetic anisotropy. In addition, design rules and boundary conditions for operating the Ni-Mn-Ga actuator material are having significant importance for evolution of performance characteristics.
