This project was originally initiated as the Monbusho Grant-in-Aid for International Scientific Research: University-to-University Cooperative Research, and then it was shifted to the JSPS Grant-in-Aid for Scientific Research (B) (2). Hence the project was jointly performed by Tohoku University group and Moscow State University researchers by inviting them to Tohoku University. Based on this joint research the following achievements were obtained.1.Shape memory effect and electromagnetic properties of ferromagnetic shape memory alloy Ni_2MnGa.(1)Peculiar magnetic properties were measured in the experiment. We clarified the temperature hysteresis of Curie temperature, and the peculiarities due to meta ferromagnetism by magnetization measurement under constant temperatures.(2)We proposed two mechanism for the explanation of the magnetic field induced strains and interpreted the strains in Ni_2MnGa, FePd and FePt alloys.(3)Polycrystalline bulk samples were fabricated by arc melting method and pulse discharge sintering (PDS) method. The materials made by PDS show better mechanical properties but less magnetic field induced strains. A single crystal bulk sample Ni_<2.08>Mn_<0.98>Ga_<0.94> exhibits giant magnetostrain over 1.0%.2.CVD diamond-like carbon (DLC) film(1)In order to make novel functional materials with SMA and DLC, a CVD equipment was newly designed and fabricated.(2)DLC with metal nanocluseters was coated on the substrates. Temperature dependency of resistivity was measured to verify the possibility of temperature sensors. We fabricated a first step demonstrator of temperature sensors using Cr contained Me-DLC.

该项目最初是作为“国际科学研究补助金：大学与大学合作研究”发起的，后来转移到JSPS科学研究补助金(B)(2)。因此，该项目由东北大学小组和莫斯科国立大学的研究人员共同执行，邀请他们到东北大学。在此共同研究的基础上，取得了以下成果：铁磁形状记忆合金Ni_2MnGa的形状记忆效应及电磁性能。(1)实验中测量了其特有的磁性能。通过在恒定温度下的磁化测量，阐明了居里温度的温度滞回，以及由元铁磁性引起的特性。(2)提出了磁场诱导应变的两种解释机制，并对Ni_2MnGa、FePd和FePt合金中的应变进行了解释。(3)采用电弧熔炼法和脉冲放电烧结（PDS）法制备了多晶体样品。PDS制备的材料具有较好的力学性能和较低的磁场诱发应变。单晶体试样Ni_<2.08>Mn_<0.98>Ga_<0.94>表现出大于1.0%的巨磁应变。(1)为了利用SMA和DLC制备新型功能材料，设计并制造了CVD设备。(2)在衬底上涂覆金属纳米团簇的DLC。测量了电阻率对温度的依赖性，验证了温度传感器的可行性。我们用含铬Me-DLC制作了温度传感器的第一步演示器。
