TL;DR: In this paper, the effects of Ag addition both on trapped field capability and mechanical properties of bulk RE-Ba-Cu-O (RE: Y, Sm) superconductors were studied.

TL;DR: In this article, the authors employed an infiltration growth (IG) process, in which liquid phase Ba-Cu-O is infiltrated into Y 2 BaCuO 5 (Y211) pellets with NdBa 2 Cu 3 O y seed at high temperatures to produce Y123 phase.

TL;DR: In this paper, the shape of the J c (H a ) curves at T = 77 K can be changed from a very pronounced fishtail behaviour to a plateau-like behaviour, yielding a nearly constant current density up to 2.5 T. The presence of small Gd-211 particles does not inhibit the function of flux pinning provided by composition fluctuations leading to a spatial scatter of the superconducting transition temperature, as long as the 211 concentration is less than 40 mol%.

TL;DR: The fracture surface morphology of top-seeded melt-grown SmBa 2 Cu 3 O x bulk superconductors after tensile tests in (100) direction at room temperature was observed using SEM as discussed by the authors.

TL;DR: In this article, the effect of nano-particle additions on superconductivity properties has been investigated and an enhancement of the critical current J C in low and intermediate field at 77 K and trapped field was discovered by the additions of the nanoparticles.
