| 中文摘要 | The magnetic configuration of Mn2NiAl ribbon has been investigated. In contrast to Ni2MnAl, the compound Mn2NiAl with considerable disorder does exhibit ferromagnetism and, due to exchange interaction competition, both ferromagnetic and antiferromagnetic moment orientations can coexist between nearest neighbor Mn atoms. This is unexpected in Heusler alloys. Regarding the mechanism of the martensitic transformation in Mn50Ni50-xAlx, it is found that increasing the Al content results in an unusual change in the lattice constant, a decrease of the transformation entropy change, and enhancement of the calculated electron localization. These results indicate that the p-d covalent hybridization between Mn (or Ni) and Al atoms gradually increases at the expense of the d-d hybridization between Ni and Mn atoms. This leads to an increased stability of the austenite phase and a decrease of the martensitic transformation temperature. For 11 <= x <= 14, Mn50Ni50-xAlx ferromagnetic shape memory alloys are obtained. (C) 2014 AIP Publishing LLC. |
