We have fabricated ${\mathrm{YBa}}_{2}{\mathrm{Cu}}_{3}{\mathrm{O}}_{7\ensuremath{-}x}$ (YBCO)/Au/Ag/PbIn edge junctions using in-plane aligned a-axis oriented films in order to study the anisotropic coupling between YBCO and PbIn. Seven junctions we

The transport and magnetic properties of epitaxial (La0.7Sr0.3)MnO3 (LSMO) films deposited on LaAlO3 (Sample L, under a compressive stress) and SrTiO3 (Sample S, under a tensile stress) are compared. The magnetic force microscope image of Sample L sh

We have measured the angular dependence of the critical current density (J{sub c}) on magnetic field and temperature in untwinned a-axis-oriented YBa{sub 2}Cu{sub 3}O{sub 7{minus}x} films. The direction of magnetic field with respect to the crystallo

We have pulsed laser deposited untwinned a-axis oriented YBa/sub 2/Cu/sub 3/O/sub 7-/spl delta// films on (100) LaSrGaO/sub 4/. From resistive measurements, the chain contribution to the total charge carrier density was estimated to be around 60%. Cr

Sr/sub 2/RuO/sub 4/ is the only known layered perovskite that is free of copper, yet superconducting. Its low metallic resistivity and excellent lattice match with YBa/sub 2/Cu/sub 3/O/sub 7-/spl delta// make it an attractive candidate for use as con

The growth process of a YBCO/LaAlO3/YBCO trilayered film made by pulsed laser deposition has been studied by high resolution transmission electron microscopy (HRTEM). The high resolution images of the cross-section samples have shown that a 7 nm laye

We present a systematic study of the surface resistance of perovskite thin films and bulk samples at microwave frequencies. The d.c. resistivity ϱ of the various samples spans three orders of magnitude. For bulk samples, we obtain the usual ϱ 1 2 d
