Nuclear magnetic resonance (NMR) is a powerful spectroscopic technique which has made tremendous advances since its inception 60 years ago. Research in this lab centers on further pushing back the boundaries of this important and fascinating field. The following doctoral dissertation comprises a series of experiments broadly grouped into three chapters, prefaced by a brief introduction.
Chapter one outlines the fundamental principles of magnetic resonance. Chapter two describes the development of two novel techniques for MRI spatial encoding which circumvent the need for conventional pulsed field gradients. Chapter three outlines a series of experiments which probe the fundamental physics of spin relaxation in xenon gas, an important tracer for medical MRI applications. The final chapter covers the progress made so far on the development of a magnetometer based on the diamond nitrogen-vacancy defect and its prospects for use as a cheap, high-sensitivity magnetic field detector for application in nanoscopic NMR imaging.
