Original Paper


The influence of pinning centers size on the superconducting properties was investigated. Through the addition of three batches of ZrO2 nano-particles with mean size of D 1=13 nm, D 2=21 nm, and D 3=85 nm, we have succeeded in incorporating effective artificial pinning centers within the YBCO matrix of the bulk superconductor. An enhancement in the flux pinning and an improvement in the critical current densities (transport critical current density J ct and magnetic critical current density J cm) were achieved. The results indicate that slight inclusions of ZrO2 can greatly enhance the flux pinning capability of samples. Comparative analyses of the critical current densities and the resulting pinning force F p for the three diameters have shown that pinning centers with finer size are much more efficient than those with a size larger than the coherence length ξ.
