Type of article: Article

Summary

A RADIO-FREQUENCY MAGNETIC SUSCEPTIBILITY APPARATUS IS DESCRIBED, WHICH IS CAPABLE OF MEASURING THE SUPERCONDUCTING TRANSITION TEMPERATURE OF INDIVIDUAL SAMPLES WITH VOLUMES AS SMALL AS 0.00002 MM3 (MASS ABOUT 0.1 MICROGRAMME) WITH A SIGNAL-TO-NOISE RATIO OF 20. THE SYSTEM USES PHASE-SENSITIVE DETECTION AND OPERATES BETWEEN 1 AND 10 MHZ. MEASUREMENTS IN LARGE DC MAGNETIC FIELDS OF ABOUT 150 KILOG ARE ALSO POSSIBLE.
