Abstract:
A study of the martensitic phase transition in the shape memory alloy 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.
