Phase Evolution of YBa2Cu3O7-xfilms by all-chemical solution deposition route for coated conductors

Phase Evolution of YBa2Cu3O7-x films by all-chemical solution deposition route for coated conductors

In order to understand the all-chemical-solution-deposition (CSD) processes for manufacturing coated conductors, we investigated the phase evolution of YBa2Cu3O7 (YBCO) films deposited by a low-fluorine metal-organic solution deposition (LF-MOD) method on CSD derived Ce0.9La0.1O2/Gd2Zr2O7/NiW. It is shown that the phase transition from the pyrolyzed film to fully converted YBCO film in the LF-M...

Near-adiabatic quench experiments on short YBa2Cu3O7− coated conductors

Minimum quench energy and normal zone propagation velocity are measured on short YBa2Cu3O7− coated conductors in self-field at temperatures ranging from 40 to 77 K. The sample is cooled via a cryocooler with a cryostat pressure of 10−4 Pa, creating a nearly adiabatic environment. A normal zone is created by pulsing a heater that is attached to the sample surface with a thin layer of alumina-fil...

The Effect of Sintering Oxygen Partial Pressure on a SmBiO3 Buffer Layer for Coated Conductors via Chemical Solution Deposition

The application of high-temperature YBa2Cu3O7−δ (YBCO) superconducting material is a considerable prospect for the growing energy shortages. Here, SmBiO3 (SBO) films were deposited on (100)-orientated yttrium-stabilized zirconia (YSZ) simple crystal substrates via the chemical solution deposition (CSD) approach for coated conductors, and the effects of sintering oxygen partial pressure on SBO f...

Mechanisms of weak thickness dependence of the critical current density in strong-pinning ex situ metal–organic-deposition-route YBa2Cu3O7−x coated conductors

We report on the thickness dependence of the superconducting characteristics including critical current Ic, critical current density Jc, transition temperature Tc, irreversibility field Hirr, bulk pinning force plot Fp(H), and normal state resistivity curve ρ(T ) measured after successive ion milling of ∼1 μm thick high-Ic YBa2Cu3O7−x films made by an ex situ metal–organic deposition process on...
