Abstract :
Based on the single-domain theory, a hysteresis model of the magnetoresistance ratio of magnetic thin films has been studied with different current-voltage configurations. The influence of the distribution of easy axes on the magnetoresistance was also studied, and results indicated that the peak value of magnetoresistance does not occur at coercivity. Results also suggested that both the multidomains and nonuniform current reduce the MR ratio
