“…the YBCO texture is very sharp (< 5 • ) on single-crystal Ag, whereas it is higher (∼ 20 • ) for the polycrystalline Ag substrates of similarly broad in-plane grain misorientations. It has been previously reported that YBCO grown on cube-textured silver by physical vapour deposition (PVD) techniques at ∼700 • C show two inplane grain orientations, but only one in-plane orientation of (110) Ag [25,26]. Since after deposition at ∼900 • C, we find only one in-plane orientation on both (100) and (110) Ag, it is clear that the temperature of deposition plays a strong role in determining the epitaxy.…”

Ultrasonic spray pyrolysis (USP) has been used to deposit thick films (up to 5 micron) of YBa2Cu3O7-x in situ on single-crystal oxide substrates, and single-crystal and textured polycrystalline Ag foil of different orientations. Epitaxial films grow with a strong level of in-plane texture on the single crystal oxide substrates (<3° full width at half maximum) and on (100) and (110) oriented Ag. Films grown under optimized conditions have onset Tc of 91 K with transition widths of ~ 6 K. The films are fully connected and Jc are ~ 1.0×104A cm-2 at 77 K and ~ 5×105A cm-2 at 20 K.

“…Ag may also be used for the next generation of YBa 2 Cu 3 O 7 tapes, since no buffer layer is required. Recent publications present the first promising results of in-plane aligned YBa 2 Cu 3 O 7 thick film grown on textured silver [10][11][12][13][14][15][16][17][18]. In-plane alignment has been obtained both on cube textured {100} 001 and on {110} 011 oriented substrates.…”

“…It is therefore very difficult to obtain a pure and sharp cube texture. So far, different authors have reported various notations of recrystallization texture in Ag after rolling and annealing [17,24,25]. No detailed systematic studies on the formation conditions and factors influencing the texture in Ag can be found.…”

A systematic study of texturing mechanisms in pure Ag is presented, the goal being to obtain a cube textured {100}001 tape that can be used as a substrate for superconducting coated conductors. It is shown that a sharp cube texture can be produced after pre-heated deformation and recrystallization. Optimal parameters are detailed. 99.99% pure Ag powder is used as starting material. Fine grained (15 µm) Ag ingots are pre-heated at 100 °C before standard cold rolling. The effect of pre-heating on deformation texture is to change the main texture from the brass orientation {110}112 to the Goss {110}001 one. The presence of a copper-type texture with relatively high values of the ODF (oriented distribution function) after the 100 °C pre-heated deformation can be understood as a slight increase of the stacking fault energy of Ag during the pre-heated deformation. The optimal annealing is achieved at 700 °C for 30 min in a primary vacuum. This leads to a sharp cube texture. The FWHM values of the three x-ray pole figures are, at no more than 10°, the smallest ever reported for cube textured Ag tapes. The formation of cube texture is interpreted in terms of orientation nucleation and orientation growth theories that play a common role during the texturing process. The stability of cube texture at high temperature up to 900 °C indicates that the tapes are suitable for epitaxial growth of superconducting oxides.

“…It has been suggested that similarly textured silver could also be used for epitaxial growth of YBCO films. However, magnetron sputtered YBCO films on cube textured silver have not shown any significant in-plane texture [9]. On the other hand, YBCO grown by PLD has only shown a strong single in-plane alignment on ( I 10) oriented silver single crystals, although from a lattice matching point of view, it is unclear why ( 1 IO) is such a suitable orientation [IO].…”

An ultrasonic mist pyrolysis system has been used to fabricate thick films of YBa2Cu30,., (YBCO) on rolled and single crystal silver substrates. The substrates were heated .to 900°C and nitrate solutions of the constituent cations were sprayed using a nitrogen carrier gas. Highly c-axis aligned YBCO films were obtained by deposition at a rate of -1pm per minute. Phase pure YBCO formed up to a limit of -6pm. For thicker films, BaCuO, and Y2BaCu05 also formed. On (110) oriented single crystal silver, the films showed in-plane alignment with a four fold symmetry, and the FWHM in the azimuthal direction of the main peaks was -3". On the polycrystalline substrate the in-plane texture showed a -20" FWHM, equivalent to that of the (110)<110> textured silver substrate. The onset of the superconducting transition was measured as -90.2"C for a sample with a film thickness of -5pm.
