Zusammenfassung:No EPR signal exists in the metallic phase of dysprosium ceramics at 300 K. In the transition to the dielectric phase a resonant microwave absorption appears, consisting of a broad symmetric line and two narrow asymmetric lines. It is supposed that narrow lines correspond to localized exciton-like complexes of the Cu super(2+)-O super(-) type (S = 1), while the wide line is connected with the ferromagnetic clusters in CuO sub(2) layers. copyright 2002 Elsevier Science B.V.
