Co-developed a new understanding of the temperature, magnetic field and field angle dependence of the critical current density in technological superconductors, dispelling two decades of superstition and bad physics.
Expanded the fundamental understanding of the origin of high critical currents in high temperature superconductor thin films and developed new classes of flux pinning additives for tailored critical current enhancement as well as new nanotechnological processes for their effective incorporation.
Introduced the first effective magnetic pinning centre into the high-temperature superconductor YBCO thereby initiating a new paradigm in flux pinning to reinvigorate a stagnating field, and co-developed a new theory of magnetic pinning in superconductors inspired by the results.
Produced the world’s only epitaxial thin films of the borocarbide series of magnetic superconductors, enabling important experiments probing electronic anisotropy and the nature of the superconducting state.
Established a pulsed laser deposition system for the synthesis of complex multinary phases from elemental targets, enabling production of hard magnetic thin films of importance to future data storage applications.
