摘要：
For certain ceramic samples of the Bi-based high-temperature superconductors, the dc field-cooling signal becomes paramagnetic in fields below a few 100 mOe. This effect correlates with an anomaly in the low-field microwave absorption. The data are consistent with orbital paramagnetic moments due to the appearance of spontaneous supercurrents in fields smaller than the lower critical field H(c1a) parallel to the CuO planes.
