摘要：
The magnetic field dependence of Meissner susceptibility of ceramics samples with different grain size was studied. It was found that the behaviour of susceptibility in sintered samples can be nonmonotonous. The model based on magnetic flux freezing when crossing the "irreversibility line" is proposed. The equation of the "irreversibility line" for the Josephson vortex system is obtained. In the framework of the model the experimental magnetic field dependence of susceptibility and the role of ceramics grain size are described in a qualitative manner.
