摘要：

High-Tc superconductors of YBa2Cu3O7 system including Y2BaCuOx grains, which play a role of the flux pinning center, were prepared by modified melt-texture-growth method. The pinning potential of the YBa2Cu3O7 pulverized into different particles size is investigated as functions of magnetic fields, the size of the Y2BaCuOx segregation and the particle size.
