Role of Ni-Mn hybridization in the martensitic transformation and magnetism of Mn(50)Ni(41-x)Sn9Cux alloys

2016 
研究了Ni-Mn杂化对Mn50Ni41-xSn9Cux合金马氏体相变温度和马氏体相磁性的影响.研究表明:在Mn50Ni41-xSn9Cux(x=0,1,3,5)合金中,随着Cu含量增加,马氏体相变温度和居里温度均降低;自发交换偏置场也随着Cu含量的增加从1182 Oe(1 Oe=79.5775 A/m)降低到0 Oe.马氏体相变温度和马氏体相磁性的变化归因于掺杂Cu削弱了体系中Ni 3d eg与Mn 3d之间的杂化.
