Abstract
Heusler alloys are known as suitable candidates for many applications due to their unique and tunable electronic structure, which influences the peculiar physical properties ranging from superconductivity, magnetocaloric, thermoelectric and magnetic shape memory effect. Alloys of the Ni-Mn-Ga family have attracted much attention for research since the early years, as it is one of the leading examples of Heusler material. Magnetic Shape Memory Alloys (MSMA) show high potential as an emerging class of smart materials that can function as both actuators and sensors for a new generation of simple and fast digital components that produce high mechanical performance in a limited space enabling the obtaining light and compact miniaturized actuators combined with cost reduction. Several areas of research focus on the development of magnetic shape memory alloys: alloy manufacturing methods, definition of properties and applications. In this context, this article presents the types of magnetic shape memory actuators reported in academic research, as well as the structural, thermal and magnetic properties of Ni-Mn-Ga alloys.
