We have fabricated series arrays of intrinsic Josephson junctions of area (2 mum)(2) in thin films of Tl2BaCaCu2O8 grown on vicinal substrates. Measurements of the distribution of the bias current at which a voltage first appears across the array sho

The effect of processing conditions on microstructure and phase development has been investigated for TlBi-1223 tapes made by a melt processing route. Increasing loss of crystallinity and phase decomposition into Tl-1212 and SrCaCu-oxides is seen for

We have performed transport measurements on bridges patterned in misaligned thin films of the superconductor Tl2Ba2CaCu2O8. There is a c-axis component of current flow along the bridge, giving rise to hysteretic Josephson-like current-voltage curves.

We have measured the transport properties of intrinsic Josephson junction arrays as a function of both temperature and magnetic field, the field being applied perpendicular to the transport current. We show that they depend upon whether the junction

We have fabricated intrinsic Josephson bridges using Tl-Ba-Ca-Cu-O thin films grown on vicinal lanthanum aluminate substrates. Measurements of the lock-in transition allow us align a magnetic field of up to 4 T with the copper oxide planes to better

A 2.4 GHz three-stage microstrip bandpass filter was designed using a miniaturized interdigital capacitor structure to reduce the configuration in size. The filter was simulated by a finite element method software and then fabricated using TBCCO supe

Linear microstrip resonators suffer from high peak current density inside the resonators which limit the power handling characteristics and hence their use in cellular transmitter applications. To realise higher power filter and combiner networks for

Tl-1223 tapes with engineering critical current densities, (E-Jc) values, of 2500Acm-2 can be routinely fabricated but the magnetic field properties are poor due to weak link effects. We have developed a partial melt processing route which results in
