Bulk samples of nominal Zn x (MgB 2 ) 1รx were prepared from the mixture of Mg, B, and ZnO in the Ar atmosphere at 900 ยฐC for 30 min, where x was 0-0.1. Critical current densities J c 's were estimated from the magnetization data using an extended critical state model. Improvement of J c was confirm
The relationship between flux pinning properties and crystallinity of MgB 2 bulks was systematically studied. Improved flux pinning properties under high fields were observed for samples with low crystallinity. Increased impurity scattering due to strain and defects in lattice corresponding to the d
