Large magnetoresistance in Ni 50 Mn 34 In 16 alloy
The authors report the observation of large magnetoresistance in Ni 50 Mn 34 In 16 alloy. This alloy undergoes an austenite-martensite phase transformation which can be strongly affected by the applied magnetic field. This latter effect produces very large magnetoresistance at relatively high temper...

). Signature of field induced shape memory effect is also observed in the magnetoresistance results. Above
