摘要
Co基非晶和Fe基纳米微晶材料中观察到巨磁阻抗效应G(MI),在传感器技和磁记录技术中具有巨大的应用潜能熏受国内外专家的广泛关注。为了对该效应的应用和开发作进一步研究,我们自行设计和制作了一套基于虚拟仪器技术的GMI测量系统。测试结果表明,该系统能够满足各类材料测定巨磁阻抗的要求。
Giant Magnetic-Impedance （GMI） has been observed in Co-based amorphous and Fe-based nanocrystalline. Close attention has been paid to it by scholars in lots of countries, since their great promising prospects in the application of sensor technology and magnetic recording technology. In order to research the mechanism of GMI effect and further develop applications, we designed a GMI measurement system based on virtual instrumentation, The experiment shows that the system is satisfied the demands of GMI detection for various materials.
