High critical temperature superconductors in the system La3-ZMezBa3Ca1amp;minus;vNcvCu7O16amp;plus;x where Meamp;equals;a rare earth or alkaline metal ion and Nc is a Mg, Cd ion
Compounds of the of the general formula La.sub.3-z Me.sub.z Ba. sub. 3 Ca.sub.1-v Nc.sub.v Cu.sub.7 O.sub.16+x, wherein Me can be a rare earth metal or an alkaline metal ion selected from the group consisting of yttrium (Y), ytterbium (Yb), sodium (Na) and Nc can be a 2+ion selected from the group consisting of magnesium (Mg) and cadmium (Cd) have been prepared as the HTSC in thin film superconductors. These compounds can be used as thin film high critical superconductors in thin film high critical temperature superconducting structures and antennas and in multilayered structures and devices such as Josephson junctions, broadband impedance transformers and both flux flow and field effect transistors.
