摘　　要：阐述了巨磁电阻效应实验原理、实验内容和实验方法,该仪器可测量巨磁电阻阻值与磁感应强度关系,并与正常磁电阻、坡莫合金磁电阻特性进行比较,仪器还提供巨磁电阻传感器特性测量及系列应用实验供教学使用.An apparatus of giant magnetoresistance effect is introduced, as well as the experimental principles, contents and methods. The relationship between the value of giant magnetoresistance and magnetic induction is measured with the apparatus. Also the theory of giant magnetoresistance effect and its characteristics compared with the normal magnetoresistance and permalloy magnetoresistanee is analyzed, a series of physics experiments using giant magneto-resistance sensor are also designed.
