Magnetostructural Coupling in Mn-Rich Heusler Mn-Ni-In Melt-Spun Ribbons

摘要：

　　The effect of In addition on the magnetostructural transition behavior and magnetocaloric effect in the Mn-rich Heusler Mn-Ni-In melt spun ribbons have been studied in the present work.With the increasing of the In content, the crystal structure of the alloys are tetragonal NM martensite (for x=7~8.5), 7M monoclinic martensite (for x=9, 9.5) and L21 austenite (for x=10, 11), respectively.It was found that the increase of the In content results in both a progressive decrease of the martensitic transformation temperature and a continuously enhancement of the austenite magnetic transition temperature.For the ribbons with In content of 9.5 at%, it shows the combination of the structural transformation and the magnetic transition.The large magnetization difference between the two phases confirms the occurrence of the field-induced martensitic reverse transformation.
