| description | High-Tc ceramics tend to lower its quality by the aging effect. The main cause of the degradation is considered to originate in the link region among the superconducting grains. The preservation and recovery of superconductivity by reinforcement of the grain boundary is an important issue for high-Tc application.
A quantitative analysis of the contribution due to the grain and link is necessary and the grained Bean model is proposed, where the superconducting phases are immersed in the matrix link superconductor. Difference of the superconducting characteristics of the grain, the link and grain content factor give a variety of deformation on the AC susceptibility curves. Comparing the observed data with the numerically computed model allows more clear insight between the grain and intergrain structure. |
