Analysis of thermo-magnetic fluctuations in Bi1.6Pb0.5Sr2−xLuxCa1.1Cu2.1O8+δ (0.000≤x≤0.125) superconductor

Effect of zirconium diffusion on the microstructural and superconducting properties of YBa2Cu3O7−δ superconductors

“…3 shows that the peak intensities of the Zr-diffused sample generally are greater than that of the pure one. The enhancement in the peak intensities may point out the enhanced grain growth and orientation of grains in the presence of the Zr ions, leading to the increase of the critical current density [34,35]. Moreover, it is another interesting point obtained from Fig.…”

Effect of Magnetic Field Direction on Magnetoresistivity, Activation Energy, Irreversibility and Upper Critical Field of Bi-2212 Thin Film Fabricated by DC Sputtering Method

“…In order to overcome these problems appeared, the flux pinning mechanism in the film should be investigated in detail. In the recent works [12][13][14][15][16][17][18][19][20][21][22][23][24], the researchers have extensively analyzed the flux pinning mechanism in the superconducting state to introduce the effective pinning centers such as planar defects, stacking faults, and microdefects, resulting in thermally activated jumps; or hopping of flux lines; or flux bundles over an energy barrier [25,26]. Over the pinning energy barrier of a structure, the flux line might be thermally activated although the Lorentz force exerted on the flux bundle by the current is smaller than the pinning force [27][28][29][30].…”
