Electromagnetic properties and structure of the YBa2Cu3−xScxOy ceramic at T>T c

The structural and electromagnetic properties of the YBa2Cu3−xScxOy ceramic with partial substitution Cu ⟶ Sc were studied experimentally. The following anomaly of magnetic properties has been found: at high frequencies the ceramic exhibits paramagnetic than diamagnetic, as in the 1–2–3 properties. This manifests itself in that the ceramic concentrates the high-frequency field rather than pushes it out. It has been established that, as the paramagnetic properties decrease and the diamagnetic properties increase, the critical temperature of the 1–2–3 ceramic increases.
