Abstract
Microwave absorption was measured in highly oriented ceramic samples o f YBa2Cu3O6.9 obtained by melt-quenching-melt growth solidification. M easurements on samples cooled down to the superconducting state in an external magnetic field permitted analysis of magnetic flux trapping. The character of the magnetic flux trapping has been found to be isotr opic despite distinct structural anisotropy of the studied materials c onfirmed by the results of x-ray analysis. An attempt to interpret the results within the model of intergrain Josephson junctions has been m ade.
