“…One micrometer thick YAlO layer was subsequently coated on the platform by SDP method. A detailed introduction of SDP technology could be found elsewhere [18]. After YAlO coatings, the RMS roughness value on the surface reached 0.2 nm, which was smoother than that of electrochemical and mechanical polishing technology [19].…”

a b s t r a c tA much simplified buffer structure, including a three-layer stack of LaMnO 3 /MgO/composite Y 2 O 3 eAl 2 O 3 , was proposed for high performance YBa 2 Cu 3 O 7-d (YBCO) coated conductors. In this structure, biaxially textured MgO films were prepared on solution deposition planarized amorphous substrate through ionbeam-assisted deposition (IBAD) technology. By the use of in situ reflection high-energy electron diffraction monitor, X-ray diffraction and atomic force microscope, the influence of deposition parameters, such as film deposition rate, ion penetrate energy and ion beam flux, on crystalline orientation, texture, lattice parameter and surface morphology was systematically investigated. Moreover, stopping and range of ion in mater simulation was performed to study the effects of ion bombardment on MgO films. By optimizing IBAD process parameters, the best biaxial texture showed u-scan of (002) MgO and F-scan of (220) MgO yield full width at half maximum values of 2.4 and 3.7 , indicating excellent biaxial texture. Subsequently, LaMnO 3 films were directly deposited on the IBAD-MgO template to improve the lattice mismatch between MgO and YBCO. Finally, YBCO films grown on this simplified buffer template exhibited a critical current density of 2.4 MA/cm 2 at 77 K and self-field, demonstrating the feasibility of this buffer structure.
