摘要
有效地调控非晶软磁材料的巨磁阻抗,能使其应用的领域更加广泛。本文研究了在大气环境下电流退火过程中Fe76Si7.6B9.5P5C1.9合金薄带纵向巨磁阻抗的变化规律,发现氧化可以调控样品的巨磁阻抗性能。通过10 min退火,样品磁性能得到明显改善,灵敏度大幅度提高;1 h退火,样品的GMI表现出良好的线性关系。
Effectively controlling the giant magneto impedance (GMI) of amorphous soft magnetic materials can expand the application fields. In this paper, the longitudinal GMI changes of the Fe76Si7.6B9.5 P5C1.9 alloy ribbon-films are studied by using current annealing in the open air. It shows that oxidize process can control the performance of the samples GMI effect. For annealing of 10 min, the soft magnetic properties are improved obviously and the sensitivity is increased greatly. For annealing of 1 h, the GMI of sample shows a good linear relationship.
