Areas and projects

As our name suggests the nano engineering and storage technology group work has a diverse range of interests from developing a fundamental understanding of the physical and magnetic properties of data storage materials through micromagnetic modeling to computationally sophisticated data recovery and error correction. Additionally we have interests in the numerical modeling of fluid dynamics for a range of applications. This diverse range of interests is reflected in an extremely active research programme where current projects include:

Data storage materials

  • Fundamental understanding of thin film magnetic exchange springs for data storage
  • Exploration of underlying causes of anisotropy distributions in granular and Bit Patterned Media (BPM)
  • Recording physics of bit patterned media
  • Characterisation of magnetic media using magneto-optical Kerr effect (MOKE) and Anomalous Hall Effect (AHE) techniques.

Graphene devices

  • Interaction between nanomagnets and graphene
  • Graphene based sensors
  • Magnetism in graphene

Micromagnetic modeling

  • Simulation of error rates in granular recording media
  • Modeling switching characteristics and error events in BPM

Recovery of recorded data

  • Simulation of the readout process for novel storage systems
  • Evaluation of read channel performance in BPM storage systems
  • Simulation of read channel performance using trellis code techniques

Computational modelling and simulation

  • Fluid-solid interaction multi-physics problems
  • Thermally-buoyed flow problems
  • Efficient multigrid preconditioning of sparse linear systems

We are delighted to receive the support of The Engineering and Physical Science Research Council (EPSRC), the European Union through the Marie Curie programme (FP7) and the US based Information Storage Industry Consortium (INSIC).
