Summary

THE VIBRATION OF THE REED IS DETECTED OPTICALLY WHICH GREATLY SIMPLIFIES THE SAMPLE STAGE AND ELECTRONIC CIRCUITRY. IT IS MADE POSSIBLE BY THE USE OF A MICROMINIATURE JOULE-THOMSON-EFFECT REFRIGERATOR WHICH MOUNTS DIRECTLY ONTO THE X-Y STAGE OF A METALLURGICAL MICROSCOPE. THE HIGH-QUALITY ROOM TEMPERATURE OPTICS OF THE MICROSCOPE CAN BE USED TO DETECT THE SMALL AMPLITUDE VIBRATION OF THE REED OVER A WIDE TEMPERATURE RANGE. THE CURIE AND NEEL POINTS OF THE MAGNETIC PHASE TRANSITIONS AND THE YOUNG'S MODULUS OF TERBIUM WERE MEASURED.
