STUDY OF SUPERCONDUCTING MATERIAL YBa2Cu3O9-δ BY POSITRON ANNIHILATION TECHNIQUE
-
Abstract
Characteristics of superconducting and semiconductor materials with the same composition have been studied at room temperature, 94K, and 77K by the positron annihilation technique. The results indicate that the phase transition of electronic structure in the superconducting material takes place in the superconducting state.
