Ni2MnGa has been carried out. Ni2MnGa is one of the group of "shape
memory effect" alloys which are currently exciting considerable interest. The
origin of this effect in the compound is in the phase change which takes place
on cooling through T = 200 K from the cubic L21 Heusler structure to a
tetragonal phase. Recently the results of band structure calculations have
been used to conclude that in Ni2MnGa the structural phase transition is
driven by a band Jahn-Teller distortion. [Continues.]
