Pulsed magnetic field-induced single twin boundary motion in Ni–Mn–Ga 5M martensite: A laser vibrometry characterization

Pulsed magnetic field-induced motion of single twin boundaries in Ni–Mn–Ga 5M martensite has been studied using laser vibrometry technique. Maximum actuation velocities of 0.25m/s for Type I and 2m/s for Type II twin boundary motion were directly observed, which corresponds to velocities of 4.2m/s a...
