| Abstract: | The testing principle of the magnetoresistive effect of metal films by the probe-method was introduced.The effect of the probe factor on the measuring result was analyzed.A high accuracy testing system was designed and made,the key control subprogram for computer was given.This system gathers the functions of sampling data,processing data and calculating parameters together,and has a friendly interface,a wide test range as well as high precision.The system software can draw or output the curve of the measuring result at computer screen or printer,and it can produce the standard data files which support some data processing software such as ORIGIN. |
