摘要
An NMR spectrometer, where the transverse ac-component of magnetization is detected by a SQUID, is described and its sensitivity is analysed. The spectrometer was developed for studies of highly polarized metallic copper in low fields, for which the main requirement was a constant gain over a wide frequency range. In this application the NMR spectra have been measured with the continuous wave frequency sweep method from below 1 kHz up to 100 kHz. © 1979.
