Abstract
The Ni43.3 Mn31.5 Fe11.7 Al13.5 ribbon was obtained by melt-spinning method and the microstructure, magnetic and magnetoresistance properties of these ribbons were studied by scanning electron microscope and vibration sample magnetometer. The reverse martensitic transformation from the weak-magnetic martensite phase to the ferromagnetic austenite was confirmed in these ribbons. A moderate negative magnetoresistance in the magnetic field of 30 kOe was obtained around the martensitic transformation, which would mainly owing to the field-induced reverse martensitic transformation. Taking into account of various properties, the present Ni–Fe–Mn–Al ribbons provide an impetus for further research.
