Summary The recently discovered intermetallic superconducting compounds with the general formula REM2B2C (M 4 Pd, Ni, Pt and RE = Y + rare earths) present a record critical temperature for intermetallic compounds and other interesting properties related to the anisotropic layered structure and to an intriguing interplay between superconductivity and magnetism when RE is magnetic. Here we present the...
Summary We designed and fabricated a Tchebysheff three-pole bandpass microstrip filter with a center frequency off= 9.5 GHz and bandwidth at —3 dB of 0.8%. The device has been made with high-quality YBa2Cu307-δ (YBCO) films deposited on LaA103 substrates by an inverted cylindrical magnetron sputtering technique. The microwave behavior of the YBCO films has been studied using a microstrip resonator...
