Abstract
We study the reasons for which the compound YBa2Cu3O y begins to lose its superconducting ability with a decrease in particle sizes to values of ∼0.1 μm. Our analysis of the results of structural and magnetic studies has allowed us to reveal changes in the parameters of the crystal structure and of the superconducting state in small particles of an HTSC and to show that the main cause of these changes is a special kind of a structural disorder peculiar only to small particles of YBa2Cu3O y and is realized as a consequence of the need for nonequilibrium conditions during their synthesis.
