Shape-Memory Alloy Magnetic Shape Memory Alloy Bar (Ni50/Mn28/Ga22 (Atomic %)) exhibits magnetic shape memory, meaning it changes shape in response to a magnetic field. With 3 variations available, this bar is used in applications like actuators, sensors and microfluidic pumps, taking advantage of its ability to undergo large deformation when exposed to a magnetic field. The magnetic shape memory effect allows for contactless actuation and sensing, making this alloy useful for developing solid state devices and MEMS.
