Dr Oliver Brooks is a Post-Doctoral Research Fellow in the Magnetic Materials Group at the University of Birmingham.


Oliver Brooks graduated with an MPhys degree (1st Class) in Physics from the Loughborough University in 2012. He later went on to study a PhD on the development the Hydrogen Ductilisation Process (HyDP) for rare earth magnets under the supervision of Professor Allan Walton and Professor Rex Harris at the University of Birmingham. This process allowed for room temperature deformation of the normally brittle Nd-Fe-B material, whilst avoiding any powder processing and improving the magnetic behaviour. During this time, Oliver and his supervisors patented HyDP and he has published several papers in this area.

Oliver currently works as a post-doctoral research fellow in the Magnetic Materials Group, primarily investigating the optimisation of HyDP and its potential for commercialisation. He also investigates the high temperature Hydrogenation-Disproportionation-Desorption-Recombination (HDDR) reaction which transforms the microstructure and magnetic properties of Nd-Fe-B materials.


  • Optimisation of microstructure and anisotropy of Nd-Fe-B materials using HyDP
  • Mechanical properties of Nd-Fe-B materials
  • Magnetic characterisation of rare earth magnets
  • Optimisation of solid/dynamic HDDR processing
