TL;DR: In this paper, the authors performed magnetic susceptibility measurements on RuSr2Eu15Ce05Cu2O10−δ (Ru1222) material and found that the magnetization versus applied field loops do not saturate even at very high applied fields, resulting in the short range magnetic order in the system, which facilitates the formation of clusters that freeze at low temperature.

TL;DR: In this paper, a combination of counter-balanced Si and C co-substitution for B, leading to a large number of intragranular dislocations and the dispersed nano-size impurities induced by the substitution.

TL;DR: By doping MgB_2 superconductor with SiC nano-particles, the authors successfully introduced pinning sites directly into the crystal lattice of Mb_2 grains (intra-grain pinning).

TL;DR: In this article, a consistent model of vortex pining and supercurrent limitation is developed and discussed, where rows of growth-induced out-of-plane edge dislocations forming low-angle boundaries (LAB's) are shown to play a key role in achievement of the highest critical current density.

TL;DR: In this article, a sugar-coated boron powder was used to improve the performance of the superconductivity of the MgB2 superconductor. But, the sugar-added powder undergoes the decomposition of sugar to, most likely, reactive carbon above O6 + 6 diffc+6 diffc.
