Abstract
The structural changes as well as the anomalies displayed by some phys ical properties in the temperature interval which precedes the martens itic transformation in Ni2MnGa compound have been studied. It is concl uded that the TA(2) soft phonon condensation at T=T-1 >T-M (T-M being the martensitic transformation temperature) is responsible for the beh aviour mentioned above.
