The Ni2In-type hexagonal MM＇X alloys is a new kind of potential magnetic phase-transition functional materi- als. Based on the magnetic martensitic transformation, they exhibit excellent magnetic-field-induced martensitic transfor- mation and magnetocaloric effects. The structure, magnetism and research history of MM＇X alloys are introduced, and, the recent investigation progress of the magnetoresponsive properties are summarized. The ideas, methods and results dur- ing the exploration and improvement of the representative MnNiGe and MnCoGe systems are clarified. The tailoring and re- alizing of the magnetostructural transitions, especially the building of Curie temperature windows for paramagnetic-ferro- magnetic martensitic transformations, are intensively shown. An outlook for the potential applications and advantages of MM＇X alloys are also given.
