Description
A study of a bulk YBCO magnetometer based on the detection of harmonics during nonlinear magnetization is reported. For a low-DC field, the amplitude of the even harmonic appearing at the pickup coil depends linearly on the DC field intensity. The performance of the magnetometer depends on the quality of the sample, and the intensity and frequency of the AC field excitation. At higher Hac, the fourth harmonic becomes more sensitive than the second harmonic. The hysteresis in the magnetometer for DC field measurement has been reported. (author). 14 refs., 3 figs
