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...

This work discusses the development of an analysis routine for evaluating nanoparticle distribution in nanocomposite thin films. YBa2Cu3O7−δ (YBCO) films were synthesized via a chemical solution deposition approach starting from colloidal YBCO solutions with preformed nanoparticles. The nanoparticles and interlayer diffusion are evaluated X-ray photoelectron spectroscopy (XPS) depth profiling c...

LaCaBaCu3O7 (La1113) is a superconductor below TC(onset)=80K and its structure is similar to the tetragonal YBCO. In this work the magnetic properties of a bulk La1113 sample are reported and compared to those of YBCO superconductor. We explore a possibly relation of this property to its particular crystalline structure, particularly to the oxygen deficiency. In contrast to a bulk YBCO, some ma...

– The superconducting current-phase relation (CPR) of Nb/Au/(001)YBa2Cu3Ox heterojunctions prepared on epitaxial c-axis oriented YBa2Cu3Ox thin films has been measured in a single-junction interferometer. For the first time, the second harmonic of the CPR of such junctions has been observed. The appearance of the second harmonic and the relative sign of the first and second harmonics of the CPR...

We have studied systematically the role of silver in improving microstructure and properties of Y1Ba2Cu3O7 YBCO thin films. We have more than doubled the grain size to nearly 1.8 m and reduced processing temperatures by incorporating Ag in the YBCO films, which is accomplished by using a composite target containing 15% by weight of Ag. These films show approximately four times higher Jc than th...

We report measurements of the temperature and power dependence of the microwave frequency intermodulation distortion (IMD) in high quality pulsed laser deposition (PLD) Yttrium Barium Copper Oxide (YBCO) on LaAlO 3 substrate. A low-temperature (T < 30 K) increase in IMD is the observation of an upturn of the nonlinear coefficient of the quadratic field dependence of the penetration depth. This ...
