论文摘要
对晶体结构,局部结构,磁性和运输特性的系统研究,以淬火和回火的ni $ _ {2-x} $ mn $ _ {1+x} $ sn合金表明Mn $ _3 $ sn类型的结构缺陷的形成是由Mn和Sn y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y和x $ x $ x $ x $ yblatte y s y y x $ yblatte y x $ yblatte x $ i的结构。抗铁矿疾病是由Mn在X部位替代Ni引起的。在脾气退火时,这些缺陷分离并分离为$ l2_1 $ heusler和$ d0_ {19} $ mn $ _3 $ _3 $ sn类型阶段。
A systematic study of crystal structure, local structure, magnetic and transport properties in quenched and temper annealed Ni$_{2-x}$Mn$_{1+x}$Sn alloys indicate the formation of Mn$_3$Sn type structural defects caused by an antisite disorder between Mn and Sn occupying the Y and Z sublattices of X$_2$YZ Heusler structure. The antisite disorder is caused by the substitution of Ni by Mn at the X sites. On temper annealing, these defects segregate and phase separate into $L2_1$ Heusler and $D0_{19}$ Mn$_3$Sn type phases.
