Sommaire:

Producing a magnetic resonance (MR) probe with single spin sensitivity and imaging capabilities would provide great insight into the nanoscale workings of interesting scientific samples, with applications ranging from healthcare to quantum information. In this talk I will give an overview of the significant progress in recent years in both ESR and NMR measurements using the nitrogen vacancy (NV) centre in diamond. In particular, I will discuss recent work done at the University of Melbourne to achieve nanoscale MR via monitoring the relaxation rate of the NV centre. In addition to potentially giving significant sensitivity improvements, this is a vastly simpler technique than previous protocols, eliminating the requirement for highly precise control of the NV centre. This opens up the prospects of high sensitivity NMR in challenging environments such as within living cells.
