The First Principle Studies on the Ferromagnetic Shape Memory Effect of Ni2YIn(Y=Fe, Co) Heusler Alloys

摘要：

　　The atom occupied sites, structures, tetragonal transformation and magnetic properties are studied by the first principles calculations.From least energy principle, the calculated equilibrium lattice parameter is 6.03 (A) and 6.00 (A) for Cu2MnAl type Ni2YIn (Y=Fe, Co) alloys, respectively.The Ni2YIn (Y=Fe, Co) alloys show steady martensitic phases at c/a=1.29 and c/a=1.36 based on the EBPs method.Ni atoms and Y (Y=Fe, Co) contribute to the total magnetic moments, and keep parallel aligned in martensitic and austenitic phases.The Ni2YIn (Y=Fe, Co) alloys are the candidates for Ferromagnetic Shape Memory Alloys.
