| Popis: | Using direct and magnetically modulated microwave absorption, aging and thermal-cycling effects have been studied in single crystals and thin epitaxial films of Y 1 Ba 2 Cu 3 O 7 fabricated by laser ablation on LaAlO 3 substrates. The aging is most likely due to oxygen loss from the surface layers since the aging effects can be nearly completely reversed by isothermally annealing the samples in oxygen. The relevance of these results to the performance of microwave devices is discussed. |
