ANOMALOUS MICROWAVE-ABSORPTION IN BI-2212 HIGH-TEMPERATURE SUPERCONDUCTORS WITH THE PARAMAGNETIC MEISSNER EFFECT

The results of the experimental study of an anomaly in low magnetic field microwave absorption in polycrystalline Bi high-temperature superconductors are presented. These results show the presence of the so-called paramagnetic Meissner effect. The data obtained are evidence for the common origin of the two effects which may occur due to the presence in the samples of weak links with inverse Josephson coupling (the pi-contacts).
