  • Article: Magnetic field-induced reverse martensitic transformation in NiMnGaCu alloy
    Panpan Li, Jingmin Wang, Chengbao Jiang, Huibin Xu
    [show abstract] [hide abstract]
    ABSTRACT: The reverse martensitic transformation was monitored by testing the x-ray diffraction patterns with increasing temperatures in an Ni46Mn33Ga17Cu4 alloy. A large magnetization change from a weak-magnetic martensite phase to a ferromagnetic austenite phase has been found on the M–T curves of heating cycle in this alloy. The reverse martensitic transformation temperatures have been lowered by 7 K under the magnetic field of 90 kOe. The magnetic field-induced reverse martensitic transformation has been confirmed at a fixed temperature in this alloy, demonstrating that another alloy performing the MFIRMT is discovered: NiMnGaCu alloy.

  • Article: Search for transformation from paramagnetic martensite to ferromagnetic austenite: NiMnGaCu alloys

    [show abstract] [hide abstract]
    ABSTRACT: Search for transformation from paramagnetic martensite to ferromagnetic austenite in ferromagnetic shape memory alloys is performed through designing NiMnGaCu alloys. The composition dependence of the martensitic transformation temperature T<sub>M</sub> , the magnetic transition temperatures T<sub>C</sub><sup arrange="stagger">A</sup> of the austenite and T<sub>C</sub><sup arrange="stagger">M</sup> of the martensite is systematically investigated. The sequence of the martensitic transformation and magnetic transition is determined. The diagram on the structural and magnetic transition in a specific system Ni <sub>46</sub> Mn <sub>25+x</sub> Ga <sub>25-x</sub> Cu <sub>4</sub> is outlined, in which a transformation from paramagnetic martensite to ferromagnetic austenite is predicted, exhibiting T<sub>C</sub><sup arrange="stagger">M</sup>≪T<sub>M</sub>≪T<sub>C</sub><sup arrange="stagger">A</sup> . Such a transformation is then experimentally achieved in Ni <sub>46</sub> Mn <sub>33</sub> Ga <sub>17</sub> Cu <sub>4</sub> alloy.
