为研究电磁材料的机、电、磁特性，设计了一种新型多功能膨胀装置。在退磁和磁化饱和状态下，Ni薄膜的弹性模量差值约为22.16%。利用新型膨胀系统，分别对Ni和PZT /Ni薄膜的机械磁性行为进行了原位测量。详细讨论了磁滞回线中材料的饱和磁化、剩余磁化和矫顽力场三个关键特性的演变过程。利用应力和磁化强度的竞争关系分析了Ni和PZT/Ni薄膜的机磁耦合行为机理。同样，利用该实验系统对PZT/Ni薄膜的电磁特性进行了原位测量。用磁弹性各向异性能量点讨论了饱和磁化、剩余磁化和矫顽力场Kerr信号的演化。本文建立了一套合适的机-电-磁胀量测量系统，为进一步了解电磁膜材料的多场耦合特性提供了良好的选择。
A novel multiple functional bulge apparatus was designed to study the mechanical-electronic-magnetic characteristics of electromagnetic materials. The elastic modulus difference effect of Ni thin film was observed and it was about 22.16% in the demagnetized and magnetization saturated states. The mechanical-magnetic behaviors of Ni and lead-titanate zirconate (PZT)/Ni films were in-situ measured by using the new bulge systems, respectively. The evolutions of three key material properties in hysteresis loop including saturation magnetization, remanent magnetization and coercive field were discussed in detail, respectively. The mechanisms of mechanical-magnetic coupled behaviors of Ni and PZT/Ni films were analyzed with the aid of the competitive relationship of stress and magnetization. Similarly, the electronic-magnetic characteristics of PZT/Ni films were in-situ measured by using this experimental system. The evolution of saturated magnetization, remanent magnetization and coercive field Kerr signals were discussed with the magneto-elastic anisotropy energy point. In this paper, a suitable mechanical-electronic-magnetic bulge measurement system was established, which would provide a good choice for further understanding the multi field coupling characteristics of electromagnetic film materials.
