The Phase Transformation and Magnetic Properties in Ni-Mn-In Alloys

Article Preview

Abstract:

The phase transformation and magnetic properties of Heusler-type Ni50Mn50-xInx (x=10~16) ferromagnetic shape-memory alloys have been systemically investigated by differential scanning calorimetry and vibrating sample magnetometry. It is found that the phase transition temperatures show a linear relationship with the In concentration and the curie temperatures of austenite phases are not sensitive to the alloy composition. The existence of large magnetization change during the magneto-structural transition is the origin of magnetic-field-induced transformation effect.
