摘要：
This paper describes an inductive magnetization sensor, designed to measure thin superconducting films (of order 3000 Angstrom) in very strong magnetic fields. For magnetic fields in the range 250-500 kG, the sensitivity of the probe is 10(-2) emu. Accuracy and high sensitivity were obtained by combining a sample extraction system, vibration isolation, and an inductive sensor with optimized flux coupling geometry. The magnetic flux coupling to the sensor was verified to exceed 70%, both by calculation and experimental calibration. (C) 1995 American Institute of Physics.
