“…Thin films of superconducting material were prepared in-situ on MgO, YSZ, and crystalline substrates using three fabrication techniques: magnetron sputtering (MS), laser ablation (LA), and metal-organic chemical vapor deposition (MOCVD) [8]- [10]. The test samples were made from films in the form of microstrips having a length of 2-9 mm, a width of 0.05-4 mm, and a thickness of 0.1-0.4 m. Depending on preparation conditions and deposition methods, films had perfect or granular structure.…”

“…They were also used to investigate short high electrical current pulse action on active materials used in highpower optically triggered superconducting switch [7]. The nonperfect ("granular") films, consisting of net from high and low order parameter regions having less than 10 , were used to investigate fast superconducting fault current limiters [5].…”

The results of a study of irreversible damage induced in microstrips made from high-thin films by high-power electromagnetic pulses is presented. It was demonstrated that at high supercritical currents, the magnetic flux flow process induces fast thermomagnetic instability. The result of this instability is local magnetic flux propagation, and subsequent irreversible damage of the high-film. The parameter = ( ) , where and are the critical damaging and superconducting-to-dissipative state transition currents, respectively, which represents the capability of the high-microstrip to withstand supercritical current, depends on the quality and critical current density of the film.

YBa2C~307.x /Ba,Sr ,-,Ti03 /LaA103 heterostructures can be used as a basis for devices with voltage control in microwave circuits.Ba,SrI-,Ti03 (x=O-O.I)(BST) thin films have been epitaxially grown on LaAlO3 substrates using injection MOCVD. The excellent crystalline quality of the obtained BST films can be proven by a FWHM of <0,2" for the rocking curve of the (002) BST reflection. An AFM study revealed flat surfaces, showing a surface roughness R, as low as Inm.YBa2Cu307.x/Ba,Srl.x TiO3//LaA1o3 heterostmctures were than optimised. The Y B~~C U~O , .~ (YBCO) layers obtained on Ba,Srl-,TiO3 films are epitaxial with a FWHM of 0.45" for the (005) YBCO rocking curve and display very promising superconducting properties of T,=92K.Finally the microwave properties of the superconducting films were studied. For YBa2Cu307.x layers directly deposited on LaA103, surface resistance values of 0 , 3 2 M were obtained, while for YBa2Cu307.x /SrTi03//LaAI03 heterostructures, higher values of ImR at 8.5GHz were measured.

“…Nevertheless, for commercial applications of YBaCuO tapes, a low cost production method is necessary. Metal organic chemical vapor deposition (MOCVD) is a good candidate because it is a high deposition rate, large-area deposition technique proven to be successful for YBCO deposition on single-crystal substrates [ 1,2]. MOCVD also has the potential for deposition of both the buffer [3,4] and superconducting layers on textured metallic substrates.…”

YBaCuO films of about 1 pm thickness have been deposited by Metal organic chemical vapor deposition (MOCVD) on biaxially textured Ni-based substrates. Different buffer layers (MgO, YSZ, CeOz), and also NiO epitaxially grown on Ni, have been tested with subsequent YBCO deposition in the same reactor. When using NiO as first buffer layer, Ni-based substrates were oxidized in a Rapid thermal processing system or in a conventional furnace previous to deposition of the second buffer layer. In the present work, we study different conductor architectures from the point of view of Tc, Jc(77K), epitaxial growth, and chemical stability of the structure.
