10 p, 380.8 KB Calibration of low-temperature ac susceptometers with a copper cylinder standard / Chen, Du-Xing (Universitat Autònoma de Barcelona. Departament de Física) ; Skumryev, Vassil (Universitat Autònoma de Barcelona. Departament de Física)
A high-quality low-temperature ac susceptometer is calibrated by comparing the measured ac susceptibility of a copper cylinder with its eddy-current ac susceptibility accurately calculated. Different from conventional calibration techniques that compare the measured results with the known property of a standard sample at certain fixed temperature T, field amplitude Hm, and frequency f, to get a magnitude correction factor, here, the electromagnetic properties of the copper cylinder are unknown and are determined during the calibration of the ac susceptometer in the entire T, Hm, and f range.
