PhD Project - Nanocrystalline Superconductivity
This project involves fundamental and applied scientic investigations into nanocrystalline high-field materials. The project is focussed on fabricating nanocrystalline YBa2Cu3O7, Bi2Sr2CaCu2O8 and Bi2Sr2Ca2Cu3O10 through mechanical ball milling, hot isostatic pressing and annealing, as well as understanding the physics of this new class of high magnetic field superconductors. Through a combination of transport and magnetic measurements, we explore the nature of "weak links" in these materials, and look at the cause for their suppression of critical current density.
