ShareNOVEL MAGNETOMETER AND THE INTERPRETATION OF LOW FIELD MAGNETIC HYSTERESIS OF HIGH-CRITICAL TEMPERATURE SUPERCONDUCTORS.
Author(s) : GOUGH G. E.
Type of article: Article
Summary
A NOVEL ELECTRONIC INTEGRATING MAGNETOMETER, BASED ON A COMPUTER CONTROLLED PHASE SENSITIVE DETECTOR, HAS BEEN DEVELOPED. THE HIGH SENSITIVITY OF THE MAGNETOMETER ENABLES ACCURATE MEASUREMENTS TO BE MADE ON MG SUPERCONDUCTING SAMPLES IN LOW FIELDS OF UP TO 50 MILLIT. A COMPUTER FITTING PROCEDURE GIVES VALUES FOR THE MAGNETIC FILLING FACTOR, THE STRENGTH OF THE ZERO-FIELD CRITICAL CURRENT DENSITY AND THE SCALING FIELD FOR A GIVEN ASSUMED FIELD DEPENDENCE OF CRITICAL CURRENT. MAGNETIZATION MEASUREMENTS ON VARIOUS CERAMIC YBCO SAMPLES, YIELD VALUES FOR BULK CRITICAL CURRENTS IN GOOD AGREEMENT WITH TRANSPORT MEASUREMENTS.
