“…It is possible that at higher density of iridates, the partial melting temperature of Bi‐2212 matrix is shifted to a much lower value, resulting in the appearance of precipitates on the film surface. This is consistent with the BSCCO phase diagram . Moreover, at higher density, Sr and Ba‐iridate diffuses into Bi‐2212, leading to increased granularity and surface roughness.…”

Phone: þ82 42 821 5451, Fax: þ82 42 822 8011 Iridate nanoparticle AIrO 3 (A ¼ Sr, Ba) incorporated Bi 2 Sr 2-CaCu 2 O 8 þ d (Bi-2212) thin films were successfully grown using pulsed laser deposition with post-growth ex situ heat treatment. Nanosized particles of SrIrO 3 (Sr-iridate) and BaIrO 3 (Ba-iridate) were deposited on top of MgO (100) substrate, followed by Bi-2212 layers to investigate their effects on the physical and superconducting properties of Bi-2212 thin films. The number of laser pulses was changed from 450 to 1800 to control the density of iridates in the Bi-2212 matrix. The composite film is then partial-melted at 890 8C for 15 min and annealed at 8508C for 5 h in ambient air. Scanning electron microscopy shows that the surfaces of thin films with iridates are more compact with minimal voids and porosity than those of pure Bi-2212 thin films. Both types of iridate incorporation suppress T c-zero of Bi-2212 thin films. Incorporating Sr-iridate in the Bi-2212 strongly affects T c-zero than those with Ba-iridate at low density. However, both iridate incorporations result in the expansion of the c-axis lattice constant and variation of Bi/Sr ratio of Bi-2212 films. On the other hand, we observed improvement of the activation energy, U 0 , as well as the selffield critical current density, J c (0), of Bi-2212 films with incorporated iridates even with suppressed T c-zero .

“…In Bi‐2212, the Bi/Sr ratio can strongly affect the c ‐axis lattice constant and T c‐zero . To determine the influence of the incorporation of Sr and Ba‐iridates on the composition of Bi‐2212 thin films, we calculated the ratio of Bi and Sr obtained from EDS measurement.…”

“…Several techniques have been employed to grow Bi-2212 films including magnetron sputtering [6], metalorganic chemical vapor deposition (MOCVD) [7], molecular beam epitaxy [8], liquid phase epitaxy [9] and pulsed laser deposition (PLD) [10]. In recent years, PLD has been the preferred method to produce films of Bi-2212.…”
