薄膜磁阻效应计算机控制自动测试方法的研究

摘要

The ultralow frequency scanning field power supply is obtained by chip microprocessors 8031 simulating triangular wave output. The thin film magnetic-resistance effect is measured automatically by four probes and six probes measure methods.%采用单片机8031来模拟三角波输出而产生超低频扫场电源，用四探针、六探针测量法，实现对薄膜磁阻效应的自动测试。
