本项目采用冲击形式的脉冲磁场和外应力，利用能量集中和快速记录的特点，研究制造磁驱动器，换能器，传感器，制冷器件的金属磁致伸缩材料和磁相变材料最接近使用状态的动态特性。比较动态特性和准静态测量参数的异同，研究不规则震动条件下的特殊物理现象，阐明动态特性的物理机制，为器件设计和制造提供理论依据。本项目还将把快速冲击用于结构相变过程中能带结构，电子结构和磁结构的转变路径，在这一领域走出一条新路。

In this project, investigation on dynamic properties of magnetostriction materials and magnetic structure transition materials under pulse magnetic field and impact condition will be performed. The dynamic parameters for manufacturing magnetic sensor, magnetic actuator, magnetocaloric devices would be compared with those measured by static methods of the devices design and manufacture. The related physical mechanics will be revealed and used for the application. In this project, we will use the impacting conditions to investigate the transition process of energy band, electronic structure and magnetic structure during the structural transition.
