Abstract :
The stray field detection of the periodically magnetic dot array is performed using a commercial giant magnetoresistance read head which is attached to a static spin stand setup. The magnetization reversal process is compared to the measurement of magnetic force microscopy image and M-H curve measured by AGM.
