摘要：

The experimental results of EPR investigations for superconducting, nonsuperconducting, n-irradiated and doped YBa2Cu3O7-delta are analysed. The resonance signals observed in superconducting samples are shown to arise from impurity phases and a variety of registered signals in oxygen-deficient samples is probably provided by different ordering schemes of oxygen. The results of investigations of the so-called low-field microwave absorption attributed to Josephson weak links both in ceramics and single crystals are discussed. EPR investigations in HTSC are summarized and the directions of the future experiments are discussed.
