Summary

The field dependences of the dynamic magnetic permeability of superconducting ceramic YBCO(7-) with various degrees of dispersion were studied. It is shown that the lower critical fields of the grains of superfine-grained ceramics are considerably higher than that for the coarse-grained samples.
