Abstract
The Josephson-junction (JJ) model in YBa2Cu3O7 sintered samples is confirmed by means of microwave absorption measurements at low magnetic field (<500 G). An explanation of measures supporting the JJ model is given. At low temperature (<7 K) experimental evidence shows that the array of junctions is driven by the magnetic field in a frozen state. A qualitative interpretation of this effect in the frame of the superconducting-glass picture is presented.
