      abstract     = {Ni$_2$Mn$_{1+x}$Z$_{1−x}$ (Z = In, Sn or Sb) undergo
                      martensitic transformation with transformation temperature
                      (TM) scaling with the average valence electron per atom
                      $(e/a)$ ratio. However, the rate of increase of TM depends
                      on the type of Z atom, with the slope of TM vs. e/a curve
                      increasing from Z = In to Z = Sb. Local structural
                      distortions are believed to be the leading cause of
                      martensitic transformation in these alloys. A careful study
                      of the Ni and Mn local structures in several
                      Ni$_2$Mn$_{1+x}$Z$_{1−x}$ alloys with varying e/a ratio
                      and the same Z atom, with the same e/a ratio but different Z
                      atoms and with the same T$_M$ but with different Z atoms and
                      different e/a ratio, revealed that the difference between
                      Ni–Mn and Ni–Z nearest neighbor distances decreases as
                      the Z atom changes from In to Sb. This decrease in the local
                      structural distortion accommodates a higher content of Mn
                      until the L2$_1$ structure becomes unstable and the alloy
                      undergoes a martensitic transformation.},
