The crystal structure of Ni 2+ x Mn 1− x Ga has been studied as a function of composition (x)
by powder x-ray diffraction. For Ni 2.24 Mn 0.75 Ga, where one-fourth of the Mn atoms are …

The electronic structure of Mn 2 NiGa has been studied using density functional theory and
photoemission spectroscopy. The lower-temperature tetragonal martensitic phase with c/a …

Using density functional theory, we show that in Mn 2 NiIn a phase transition from cubic to
tetragonal structure results in a lowering of the total energy, indicating occurrence of …

Recently, Liu [Phys. Rev. B 74, 054435 (2006)] published the electronic structure of Mn 2
NiGa by using ab initio spin-polarized density functional theory. In the martensitic phase …

Powder x-ray diffraction study of Mn 2 NiGa ferromagnetic shape memory alloy shows the
existence of a 7 M monoclinic modulated structure at room temperature (RT). The structure …

We have studied the effect of Fe addition on the structural and magnetic transitions in the
magnetic shape memory alloy Ni-Mn-Ga by substituting systematically each atomic species …

Ni 2 MnGa exhibits ideal ferromagnetic shape memory properties, however, brittleness and
a low-temperature martensite transition hinder its technological applications motivating the …

The premartensite phase of shape memory and magnetic shape memory alloys (MSMAs) is
believed to be a precursor state of the martensite phase with preserved austenite phase …
