本文报道了在Ni_（50）Mn_（34）In_（16）合金中观察到的大磁阻效应。这种合金经历了马氏体相变，这可以强烈地影响所施加的磁场。后一种效应在相对高的温度下产生非常大的磁阻（例如，250 K）。在磁电阻实验中还观察到了场致形状记忆效应的特征。在225 K以上，场致形状记忆效应被发现是由在H-T相空间中穿过的路径，以达到目标温度的影响。(c)2006年，美国物理学会。
The authors report the observation of large magnetoresistance in Ni50Mn34In16 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 temperatures (e.g., 250 K). Signature of field induced shape memory effect is also observed in the magnetoresistance results. Above 225 K, the field induced shape memory effect is found to be affected by the path traversed in the H-T phase space to reach the target temperature. (c) 2006 American Institute of Physics.
