Control of Superconductivity in Cuprate/Manganite Heterostructures
… In this project, devices incorporating cuprate/manganite heterostuctres were successfully fabricated to study the effects of spin transport on the high temperature superconductor, YBCO. Deposition of such oxide ferromagnet/superconductor(F/S) multilayers using the ‘eclipse’ pulsed laser …

Large-shift Raman scattering in insulating cuprate materials
… near the charge-transfer gap in insulating cuprate materials, including the T' phase materials (R2Cu04, R=Gd, Eu, Sm, Nd, Pr), T phase La2Cu04, and 123 phase PrBa2Cu3Cu06 and YBa2Cu3Cu06+x· For all of these materials, several features are observed near 12000 cm-1 (-1.5 eV) with A2g, B1g, and …

Temperature dependence of impurity resonances in cuprate superconductors
In conventional superconductors the superconducting gap in the electronic excitation spectrum prevents scattering of low energy electrons. In high temperature superconductors (HTS) an additional gap, the pseudogap, develops well above the superconducting transition temperature Tc. The identity of …

Investigation of renormalization effects in high temperature cuprate superconductors
… work renormalization in two families of high Tc cuprates have been studied. Along the diagonal of the two-dimensional BZ, the renormalization effects are represented by an unusual band dispersion that develops a so-called ‘‘kink’’. In the vicinity of the (pi, 0) point of the BZ, where the order …

Low Energy Electronic Raman Scattering in Cuprate High Temperature Superconductors
The temperature dependence of the 2$\Delta$-peak in overdoped Tl-2201 implies that the superconducting gap opens very rapidly below the critical temperature. The measured peak intensity as a function of temperature, however, shows an anomalous behavior. A magnetic field is observed to affect Raman …

Evolution of the excitation spectrum of cuprate superconductors with doping and temperature
… by which d-wave superconductivity in the cuprates emerges and is optimized by doping a Mott insulator is one of the major outstanding problems in physics. A key unresolved question in this field is how the strength of electron pairing evolves as a function of doping and temperature and …

Exploring exotic superconducting order in La-based cuprate materials using Josephson interferometry
Josephson junctions are especially useful devices for studying exotic superconducting materials, because the transmission of superconductivity through a junction depends on the difference in phase of the superconducting order parameter across the junction. We present the results of two measurements …

Controlling and understanding electro-chemo-mechanical properties of layered cuprate thin films
Surface exchange kinetics are a key indicator of performance for electrochemical devices including solid oxide fuel cells. Due to broad flexibility in dopant selection and concentration, mixed ionic-electronic conducting (MIEC) ABO₃ perovskite oxides have been extensively explored as model systems …

Increased critical current density in rapidly grown RE-based cuprate superconducting coated conductors
Coated conductor wire using superconducting Rare-earth-Ba2Cu3O7-x is a technology capable of producing many exciting new and improved devices, with applications from MRI magnets to fusion power plants. However, to be successfully commercialised the cost of performance of the wires must be improved. …
