Abstract

Advances in the field of superconductivity are mainly due to the ability to prepare single-phased samples with high critical temperature (T_c), high critical current density (J_c) and high critical magnetic field (H_c). Films played a big part in some of these advances. Several methods, such as sol-gel method, spray pyrolysis, melt-quenching method and hot-pressing method, have been tried in preparing good quality thick films.
Spreading of pastes is also one method used in preparing high-T_c superconductor thick-films (thickness > 1 μm). These high-T_c superconducting thick-films are used for coating radio-frequency (rf) devices, a good example being the high-T_c superconductor-coated cavity for a Hydrogen Maser. These films could also be used for magnetic shielding like the shielding chambers developed by several Japanese companies.
Aside from utilizing ceramic technologies in the preparation of superconducting films, doping (either by substitution or addition) of metallic elements into the superconducting system have also been conducted. Parañal, et al., investigated the effects of doping the 2223 phase of the BSCCO system with ruthenium (Ru). They reported that the introduction of ruthenium lowers the T_c of the BSCCO system and that there exist an optimum amount of ruthenium that could be introduced into the said system.
In this paper, the characterization of Bi-Sr-Ca-Cu-Ru-O thick films prepared by spreading of paste was conducted. Ruthenium content was varied from x = 0.1 to x = 0.5 with an interval of 0.1. XRD, ρ-T and SEM analyses were conducted in order to characterize the films.
