abstract = {The martensitic transition temperature of the Ni–Mn–Z
(Z = Ga, In, Sn or Sb) generally scales with the average
valence electron per atom $(e/a)$ ratio. The $(e/a)$ ratio
can be increased either by increasing Ni content in lieu of
Mn or Z (Ni-rich) or by substituting Mn for Z (Mn-rich).
While the Mn-rich alloys display the expected scaling
behaviour of the martensitic transition temperature, the
Ni-rich alloys, with the exception of Z = Ga alloys, do not
exhibit any dependency on the $(e/a)$ ratio. By carefully
studying and comparing the structure, local structure and
the physical properties of the Ni-rich and Mn-rich
Ni–Mn–Ga and Ni–Mn–Sn alloys, the cause of the
difference in behaviour is identified. The off-stoichiometry
brought about by increasing the Ni or Mn content, results in
the formation of a new local structural environment in
addition to the Heusler-like environment. If either of the
two local structural environments is martensitic, then the
resulting Ni-rich or Mn-rich alloy also exhibits martensitic
transformation.},
