“…As a class, rare-earth oxides have fascinating physical properties that offer potentials for versatile technological applications, for example, as a lattice match buffer layer for superconducting coatings, a protective coating in sever environment, fuel cell, high-dielectric insulators, and as materials for nuclear reactors [1][2][3][4][5][6][7][8][9][10]. As most other rare-earth oxides, Er 2 O 3 has attracted a lot of attention due to its leading properties and various applications such as magnetic and luminescent materials in solid-state laser [11,12].…”

The sol-gel technique was used to synthesize Er 2-x Co x O 3 (0.0 B x B 0.30) mixed oxides to analyze structural and magnetic properties. The Rietveld analyses show that Er 2-x Co x O 3 nanoparticles up to x = 0.1 have single phase, for x C 0.2 Co 3 O 4 phase appears. Preferential cationic distribution between the nonequivalent sites 8b and 24d is found for all samples. A systematic variation is found in the average maximum strain with composition x. The magnetic analysis showed that super-paramagnetism is the reason of ''S''-shaped hysteresis loops and also non-zero magnetic moments. Both Mr and Ms increased with increasing concentration of Co ?2 .

Zn 1−x Ni x O precursor solutions with a different ratio (x = 0.01-0.03) were prepared by sol-gel synthesis using Zn and Ni based alkoxide. Reel-to-reel sol-dip coating method was used to grow Zn 1−x Ni x O films. Zn 1−x Ni x O powders and films, annealed at various temperatures, were tried to observe the doping ratio and temperature effects on magnetic and microstructure properties. The surface morphologies of all samples were characterized by ESEM and EDS. The crystal structures of the ZnNiO powders were characterized using 2θ -θ x-ray diffraction (XRD). The alterations of the lattice parameters have been obtained by the TREOR program. ESR spectra of Zn 1−x Ni x O powder samples were collected at room temperature. The magnetization and microstructure of the powders and films with different dopant ratios, temperature, and the time of annealing process are presented.

“…Hence, buffer layers are absolutely necessary for coated conductor designs. Many buffer layers, including lanthanum zirconate (LZO) [2,3,4,5,6], cerium oxide (CeO 2 ) [7,8,9,10] and other lattice-matched buffer layers [11,12,13,14,15,16,17,18,19,20] which are prepared basically using solution-based methods have been used. These buffer layers should not only stop diffusion but also transfer the epitaxial texture of Ni-5% W substrate to the superconducting layer.…”

“…Owing to the high cost of multiple buffer layer depositions of LZO and CeO 2 , researchers have focused on preparing a single buffer layer with almost 0% lattice mismatch with YBCO and it was reported that the in-plane orientation of YBCO can be improved with these lattice matched buffer layers [11,12,13,14,15,16,17,18]. …”

Aqueous Chemical Solution Deposition of Novel, Thick and Dense Lattice-Matched Single Buffer Layers Suitable for YBCO Coated Conductors: Preparation and Characterization

In this work we present the preparation and characterization of cerium doped lanthanum zirconate (LCZO) films and non-stoichiometric lanthanum zirconate (LZO) buffer layers on metallic Ni-5% W substrates using chemical solution deposition (CSD), starting from aqueous precursor solutions. La2Zr2O7 films doped with varying percentages of Ce at constant La concentration (La0.5CexZr1−xOy) were prepared as well as non-stoichiometric La0.5+xZr0.5−xOy buffer layers with different percentages of La and Zr ratios. The variation in the composition of these thin films enables the creation of novel buffer layers with tailored lattice parameters. This leads to different lattice mismatches with the YBa2Cu3O7−x (YBCO) superconducting layer on top and with the buffer layers or substrate underneath. This possibility of minimized lattice mismatch should allow the use of one single buffer layer instead of the current complicated buffer architectures such as Ni-(5% W)/LZO/LZO/CeO2. Here, single, crack-free LCZO and non-stoichiometric LZO layers with thicknesses of up to 140 nm could be obtained in one single CSD step. The crystallinity and microstructure of these layers were studied by XRD, and SEM and the effective buffer layer action was studied using XPS depth profiling.
