Abstract
By measuring the magnetization hysteresis loops and the remanent magnetization relaxation for a melt-textured-growth YBa2Cu3O7−δ bulk with two different oxygen concentrations, we found that the extra oxygen deficiencies enhance the flux pinning and the fishtail effect in low and intermediate temperature region. This strongly suggests that the fishtail effect is related to the elementary pinning centers. A model concerning the nonuniform distribution of upper critical field among the pinning sites is proposed to explain the fishtail effect. Finally, we present some evidence to support this model.
