Superconducting MgB2 thin films were prepared in situ using a combination of rf magnetron sputtering of B and thermal evaporation of Mg. The films exhibited Tc of up to 36 K. The microwave measurements were performed on 14 × 14 mm2 films using both

We report on two approaches to the in situ synthesis of superconducting MgB 2 thin films. In the first approach, Mg and B were simultaneously sputtered from two separate planar targets. The substrate temperature T s was limited to a small range of 29

Ultra-thin CeO2 films with thicknesses in the range of 0.3–10 nm were deposited on r-plane sapphire substrates by sputtering. The growth of the films was investigated by X-ray diffraction measurements and by Rutherford backscattering spectroscopy.

Two-dimensionally (2D) ordered arrangements of Au micro-discs formed on the surfaces of TiO2 and SrTiO3 after “patterned” ion implantation. Cross-sectional TEM revealed that the Au micro-discs consisted of Au nanoparticles with a very narrow dept

The growth of Ce-Y-Zr-O (CYZ) buffer layers for YBa/sub 2/Cu/sub 3/O/sub 7-/spl delta// deposition on textured Ni-tapes was studied under idealized conditions on [100]-SrTiO/sub 3/ (STO) single crystals and epitaxial Ni films and under real condition

HF power-induced nonlinear effects, including the two-tone intermodulation distortion (IMD), were examined by using 2.3 GHz microstrip resonators prepared from double-sided YBa/sub 2/Cu/sub 3/O/sub 7-x/ (YBCO) and GdBa/sub 2/Cu/sub 3/O/sub 7-x/ (GBCO

CeO2 thin films were prepared on amorphous quartz glass substrates by the ion beam assisted deposition (IBAD) technique at room temperature. In order to control both the in-plane and out-of-plane texture of the films, a special geometrical arrangemen

The absolute values of the London penetration depth λL, were measured in epitaxial (001) YBa2Cu3O7−x (YBCO) thin films prepared by simultaneous sputter deposition on both sides of 3 in. r-cut sapphire wafers buffered with thin (001) CeO2 layers. T

We present measurements of the unloaded quality factor of superconducting microstrip resonators at 77 K and 3.86 GHz. The resonators were made of 0.3 μm thick YBa2Cu3O7 films with a transition temperature of 90 K on both sides of ceria-buffered 3 in
