只提供摘要形式。磁场传感器对于生产线、智能交通系统、安防系统等自动化功能的构建具有重要意义。正交磁通门机构提供了小型化的低成本磁传感器，可以集成在紧凑的电子系统中。作者提出了一种新的正交磁通门工作模式——基模，在这种模式下，与传统的正交磁通门机构相比，铸态非晶线芯可以获得更大的线性响应和更高的灵敏度，而正交磁通门机构的二次谐波是外加磁场的度量。然而，当磁各向异性存在时，非晶导线在非周向上可能会产生偏移，并且输入输出响应曲线相对于原点变得不对称。本文提出了一种解决这一问题的方法。
Summary form only given. Magnetic field sensors are important for building automated functions in production lines, intelligent transportation systems, security systems and so on. The orthogonal fluxgate mechanism provides miniaturized low-cost magnetic sensors which can be incorporated in a compact electronic systems. The author proposed a new operating mode, fundamental mode, for the orthogonal fluxgate in which greater linear response and higher sensitivity can be obtained with an as-cast amorphous wire core compared to the conventional orthogonal fluxgate mechanism where the second harmonic is a measure of applied magnetic field. When the magnetic anisotropy is present, however, in an amorphous wire at off circumferential direction, the offset may arise and the input-output response curve becomes asymmetric with respect to the origin. In this paper, a method is presented to solve this problem.
