Dr Tom Hayward
Senior Lecturer in Materials Physics
Tom is a Senior Lecturer in Materials Physics. He has been a member of the group since joining as a post-doctoral researcher in 2008. Tom’s research is focused on studying the properties of ferromagnetic nanostructures both to gain a better understanding of their fundamental behaviour and to develop new technological applications. He uses both experimental techniques and numerical micromagnetic simulations. His current research includes projects on neuromorphic and stochastic computing with nanoscale magnetic materials and the strain control of magnetic devices.

Controlling acoustic metamaterials
We are working in collaboration with the University of Exeter to combine Surface Acoustic Waves (SAWs) with Ferromagnetic Resonance (FMR) to create acoustic metamaterials. Surface acoustic wave devices have been extensively utilised in modern technology, being used as filters, sensors and for signal… -
Emergent Domain Wall Behaviour In Interconnected Nano Ring Arrays
This project investigates emergence arising from domain wall interactions at junctions between connected nano rings. The DW population of arrays can be analytically modelled against the probability of interactions occurring. Methods to measure the magnetisation of the array (itself linked to domain… -
Monitoring of Intermediate Level Waste (ILW) Packages using Magnetic Sensors
The project focuses on an alternative method to monitor Intermediate Level Waste (ILW) packages (which are securely stored in nuclear-licensed sites) until they can be safely disposed of in a Geological Disposal Facility (GDF). The timescales associated with developing a GDF storage could be up to… -
SpinENGINE
SpinENGINE is an EU-funded programme that brings together leading research groups from across Europe to explore massively-parallel computing frameworks based on the emergent behaviour of nanomagnetic ensembles. Project partners include researchers from Norwegian University of Science and Technology… -
Suppression of Stochastic Domain Wall Pinning Through Modified Gilbert Damping
This project investigates the stochastic behaviour of domain walls interacting at pinning sites within soft-ferromagnetic nanowires. Domain walls driven by externally-applied magnetic fields can undergo changes in their configuration. This changing structure can give rise to different…
