Composition of Pulsed-Laser-Deposited Y-Ba-Cu-O and Ba-K-Bi-O Thin Films
The composition of pulsed-laser-deposited Y-Ba-Cu-O and Ba-K-Bi-O thin films is shown to be strongly affected by target conditioning, gas pressure, and targetsubstrate distance. For both compounds, ablation from a freshly sanded target surface results in films with an excess of the more volatile elements. The concentration of these volatile elements in the films decreases until the system reach...
متن کاملPraseodymium valency from crystal structure in Pr-Ba-Cu-O and (Y-Pr)-Ba-Cu-O single crystals
2014 The substitution of Pr to Y leads to materials with a general formula (Y1-vPrv)(Ba2-x’Prx’)(Cu3-y~y)O6+x’/ 2-y+z and with a structural transition around x = v + x’ ~ 0.5. For x ~ 0.5 the crystals are orthorhombic, Y-Ba-Cu-O type, but with a lowered distortion. For v ~ 0.5 the crystals are tetragonal, La1.5Ba1.5Cu3O7 ± z type, with the characteristic tri-twinning of this phase. The Pr valen...
متن کاملKosterlitz-Thouless transition and conductivity fluctuations in Y-Ba-Cu-O thin films.
Kosterlitz-Thouless properties of c-axis-oriented high-T, superconducting YBa2Cu307 „ thin films were examined. The current-voltage characteristics over a wide current range obeyed a power-law relationship. The exponent u(Tj showed a "universal jump" at T, . The exponential inverse-square-root reduced-temperature dependence of the resistance above T, was consistent with a two-dimensional (2D) b...
متن کاملProperties of Mg-doped Nd-Ba-Cu-O generic seed crystals for the top seeded melt growth of (RE)-Ba-Cu-O bulk superconductors
We have recently developed a new generic seed crystal that has been used successfully to fabricate any oriented, single grain (RE)-Ba-Cu-O bulk superconductor by a cold seeding technique. In this paper we report the chemical, structural and microstructural properties of these seed crystals, including the variation of melting point, crystallographic parameters and volume fraction of Mg-rich incl...
متن کاملPyroelectric effect in Y–Ba–Cu–O thin films under laser illumination
The thermoelectric response of amorphous, semiconducting Y–Ba–Cu–O thin films was investigated by illumination with 150 ps optical pulses at 1064 nm and with a continuous wave at 493 nm ~argon laser!. The measured unbiased voltage response was consistent with pyroelectricity. At high pulse energies, the voltage response saturated due to the saturation of the spontaneous polarization. The pulsed...
