一、引言平面霍尔效应是半导体的一种电流-磁效应。戈德堡(Goldberg)等人最早对它做了研究。其后,凡采用霍尔效应法精确测量磁场中的小分量或大梯度非均匀场的各分量时,都对平面霍尔效应影响测量准确度的问题予以注意。近年来有若干文献专门探讨了这 I. INTRODUCTION Plane Hall Effect is a current-magnetic effect of semiconductors. Goldberg and others first studied it. Afterwards, attention should be paid to the problem of measuring the accuracy of the planar Hall effect when using the Hall effect method to accurately measure the small components of the magnetic field or the components of the large gradient non-uniform field. In recent years there have been several articles devoted to this
