1. The isostatic pressure processing of high Tc superconductors and their properties
Abstract : The high Tc superconductors are highly anisotropic, ceramic materials which makes it difficult to sinter them at atmospheric pressure to full density. High porosity is detrimental to their mechanical and electrical properties, so the use of isostatic pressures was used to give higher density materials with improved properties. READ MORE

2. Resonant Inelastic X-ray Scattering Studies on Quasi-Two-Dimensional Superconducting Materials
Abstract : Unconventional superconductivity is one of the many fascinating research areas of condensed matter physics. Understanding the superconducting pairing mechanism and its connection with other competing states remains unclear. READ MORE

3. The Functional Microstructure of Al/AlOx/Al Tunnel Junctions
Abstract : Josephson junction as a novel superconducting electronic component plays an important role in most small-scale superconducting systems. Particularly the Al/AlOx/Al tunnel junction, a high-performance junction made with a well-established microfabrication technology, is widely used as a building block of many quantum circuits.

4. Ramp Josephson junctions based on NdBa2Cu3O7-δ electrodes and PrBa2Cu3O7-δ barriers
Abstract : We report on smooth high quality c-axis orientedNdBa2Cu3O7-δ (NBCO) superconducting thin filmsgrown on (001) SrTiO3 substrates using pulsed laser deposition.The transition temperature of these NBCO films was around 89.5 Kand the root-mean-square (RMS) surface roughness was 0.75 nm for150 nm thick films.

5. The paramagnetic Meissner effect
Abstract : The low field dynamics of some high temperature superconductors have been studied experimentally, using SQUID magnetometry. The research has been focused on the so called Paramagnetic Meissner Effect (PME), a phenomenon seen in some high temperature superconducting cuprates. READ MORE
