As. Lagutin et al., A PROBE FOR MAGNETIZATION MEASUREMENTS OF THIN SUPERCONDUCTING FILMS IN PULSED HIGH MAGNETIC-FIELDS, Review of scientific instruments, 66(8), 1995, pp. 4267-4270
This paper describes an inductive magnetization sensor, designed to me
asure thin superconducting films (of order 3000 Angstrom) in very stro
ng magnetic fields. For magnetic fields in the range 250-500 kG, the s
ensitivity of the probe is 10(-2) emu. Accuracy and high sensitivity w
ere obtained by combining a sample extraction system, vibration isolat
ion, and an inductive sensor with optimized flux coupling geometry. Th
e magnetic flux coupling to the sensor was verified to exceed 70%, bot
h by calculation and experimental calibration. (C) 1995 American Insti
