✦ Synopsis

Magnetic susceptibility anomaly during the premartensitic transformation in Heusler alloy Ni 2 MnGa is an important physical property and has been investigated in the present work by using Green's function technique based on the magnon-TA phonon interaction model. The results of the numerical calculation shows that this kind of anomalous effect is wavevector-and magnetic-field dependent.
