I am an associate professor of materials physics in the Department of Physics at Durham University, with a research focus primarily in experimental thin-film magnetism and spintronics. My expertise covers thin-film deposition, and broad structural, magnetic and electrical analysis of thin-film materials and devices, including measurement instrumentation and automation. My research interests cover a variety of phenomena that arise due to the presence of interfaces in magnetic layered structures, including spin-pumping, current-driven magnetization reversal, and proximity induced magnetism – and often make use also of x-ray and neutron scattering at central facilities including Diamond Light Source and ISIS neutron source.

Ferromagnetic Resonance Spectroscopy: Measurement and Analysis of Magnetization Dynamics

I will give an overview of magnetization dynamics starting from the by-this-point-hopefully-now-familiar Landau-Lifshitz-Gilbert equation in various incarnations which describe the precessional magnetization dynamics, through to the various derived formalisms that are used to model and analyse experimental ferromagnetic resonance data. I will introduce, compare, and contrast the key experimental approaches which are frequently encountered in the literature, the analysis and interpretation of  measurement results, and highlight the information which may be extracted in each case.
