Probing Structural and Magnetic Instabilities and Hysteresis in Heuslers by Density Functional Theory Calculations Academic Article uri icon

abstract

  • Martensitic transformations of rapidly quenched and less rapidly cooled Heusler alloys of type NiMnX with X=Ga, In, and Sn are investigated by ab initio calculatioms. For the rapidly cooled alloys, we obtain the magnetocaloric properties near the magnetocaloric transition. For the less rapidly quenched alloys these magnetocaloric properties start to change considerably, each alloy transforms during temperannealing into a dualphase composite alloy. The two phases are identified to be cubic NiMnX and tetragonal NiMn.
