Type of article: Article

Summary

A HALL PROBE WAS INSERTED INTO THE MAGNET OF AN OPTICALLY DETECTED MAGNETIC RESONANCE (ODMR) SPECTROMETER TO STUDY RESIDUAL FIELD AT ZERO CURRENT, HOMOGENEITY, AND HYSTERETIC EFFECTS. RESIDUAL FIELDS WERE ON THE ORDER OF 10 MILLIT AT ZERO CURRENT. THE MAGNET WAS HOMOGENEOUS TO WITHIN ONE PART IN 8,000 OR BETTER OVER A REGION OF 25 MM ALONG ITS VERTICAL AXIS. SEVERAL HYSTERESIS LOOPS WERE STUDIED FOR FIELD SWEEPS. THE LARGEST SHIFTS WERE ABOUT 10 MILLIT. USING THE INFORMATION COLLECTED, RECOMMENDATIONS ARE MADE ON HOW TO IMPROVE PRECISED FIELD MEASUREMENTS FOR ODMR.
