YBa2Cu3O7-delta (YBCO) films with Zr doping have been prepared successfully by the trifluoroacetate metal-organic deposition (TFA-MOD) method through dissolving Zr acetylacetonate into the precursor solution. Yttria-stabilized zirconia(YSZ)nanoparticles were detected in the doped YBCO films by XRD. From the analysis of XRD omega and phi scans, the doped films have better out-of-plane and in-plane textures than those of the un-doped YBCO film. Although the doped YBCO films have lower T-c than that of the un-doped YBCO film, a very significant enhancement of normalized J(c) is displayed as compared to the undoped film at applied fields, indicating that an effective pinning force …

This article discusses the results of transmission electron microscopy ~TEM!-based characterization of strontium-doped lead zirconate titanate ~PSZT! thin films. The thin films were deposited by radio frequency magnetron sputtering at 3008C on gold-coated silicon substrates, which used a 15 nm titanium adhesion layer between the 150 nm thick gold film and ~100! silicon. The TEM analysis was carried out using a combination of high-resolution imaging, energy filtered imaging, energy dispersive X-ray ~EDX! analysis, and hollow cone illumination. At the interface between the PSZT films and gold, an amorphous silicon-rich layer ~about 4 nm thick! was observed, with the film composition …

We report the first instance of deposition of preferentially oriented, nanocrystalline, and nanocolumnar strontium-doped lead zirconate titanate (PSZT) ferroelectric thin films directly on thermal silicon dioxide. No intermediate seed or activation layers were used between PSZT and silicon dioxide. The deposited thin films have been characterised using a combination of diffraction and microscopy techniques.

Nd0.1Bi0.9FeO3 /Bi2FeMnO6 bilayered films were deposited on Pt/Ti/SiO2 / Si substrate by pulsed laser deposition method. BiFeO3 is antiferromagnet while BiMnO3 is ferromagnet, the ordering of –Mn–O–Fe–O–Mn– is expected, which will induce the ferromagnetic interation in the film. The film shows typical ferromagnetic properties with the transition temperature of Tc of 440 K. The room temperature (RT) ferroelectric polarization was also observed, suggesting that the film is a promising RT multiferroism.
