摘要：

The magnetic and structural transformations in the Heusler-based system Ni0.50Mn0.50-xInx are studied in the composition range 0.05 <= x <= 0.25. While the cubic phase is preserved in the range 0.165 <= x <= 0.25, we find the presence of martensitic transformations in alloys with x <= 0.16. In a critical composition range 0.15 <= x <= 0.16, the magnetic coupling in both austenitic and martensitic states is ferromagnetic. Magnetic field-induced structural transitions are also found in the x=0.16 alloy, whereby the structural transition temperature shifts by 42 K in a field of 50 kOe.
