This PhD project at the University of Bristol focuses on high-temperature superconductivity in nickel-oxides, specifically the recently discovered La3Ni2O7, which represents a new class of unconventional superconductors alongside cuprates and iron-pnictides. The research aims to understand the mechanisms behind superconductivity in these materials, with a particular emphasis on electronic interactions and the conditions that enable superconductivity at or above ambient temperatures. The project involves experimental studies including transport, magnetic, and crystallographic measurements to extract key superconducting parameters such as coherence length, London penetration depth, critical current density, and the nature of the superconducting gap.

The work will also explore whether multiple gaps exist in the superconducting state, providing insights into the pairing mechanisms. The project benefits from close collaboration with Dr Dharmalingam and Prof. Boothroyd at the University of Oxford, leveraging expertise in crystal growth and high-pressure studies. Students will have the opportunity to work with novel nickelates synthesized in both Bristol and Oxford, aiming to discover materials that exhibit superconductivity at ambient pressure through chemical structure tuning.

The School of Physics at Bristol offers a vibrant research environment, with a strong track record in research excellence and a supportive graduate community.
