We report a detailed investigation of the ${\mathrm{Ni}}_{2}\mathrm{Mn}\mathrm{Ga}$ shape memory alloy through magnetic, electronic, and thermal measurements. Our measurements anomalous Nernst effect (ANE) reveal that this technique is very sensitive to onset premartensitic transition in sharp contrast other transport With ANE being changes at Fermi surface, we infer on link between structural modulations modulation surface via its nesting features, with magnetic field induced strain mediating mechanism.
