In the recent development of a high-TC rf SQUID magnetometer, Zhang et al. used a SrTiO3 substrate resonator with a YBCO thin film flux concentrator on it. The effective area was improved by a flux concentrator. However, there was no study of the resonant frequency of the substrate resonator. In this work, the frequency-dependent flux noise of a high-T C rf SQUID coupled to a substrate resonator was investigated. The results were analyzed with the noise theory. The optimization of the SQUID with a substrate resonator and its flux noise are discussed.
