Effect of carbon nanotube doping on critical current density of MgB2 superconductor [PDF]
, 2003 The effect of doping MgB2 with carbon nanotubes on transition temperature, lattice parameters, critical current density and flux pinning was studied for MgB2-xCx with x = 0, 0.05, 0.1, 0.2 and 0.3. The carbon substitution for B was found to enhance Jc in

Energy localization in an atomic chain with a topological soliton
Physical Review Research, 2020 Topological defects in low-dimensional nonlinear systems feature a sliding-to-pinning transition of relevance for a variety of scenarios, ranging from biophysics to nano- and solid-state physics. We find that the dynamics after a local excitation results

Comparative study of flux pinning, creep and critical currents between YBaCuO crystals with and without Y2BaCuO5 inclusions [PDF]
In the Y-Ba-Cu-O system, YBa2Cu3O(x) phase is produced by the following peritectic reaction: Y2BaCuO5 + liquid yields 2YBa2Cu3O(x). Through the control of processing conditions and starting compositions, it becomes possible to fabricate large crystals ...
