Welcome to the website of the Sheffield Centre for Advanced Magnetic Materials and Devices (SCAMMD) within the Department of Materials Science and Engineering, University of Sheffield.

The Centre uses experiment and simulation to investigate fabrication, application and basic understanding of magnetic materials. Current activity includes:

  • magnetic microelectromechanical system (MagMEMS) biosensors
  • spin-wave propagation and organic spintronics
  • magnetic nanowires for information technology, biological and atomic physics applications
  • exchange bias in magnetic thin films
  • thin film magnetostriction
  • bulk hard and soft magnetic materials
  • atomistic and micromagnetic simulation methods
International Visit
Thursday, 31st March 2016
Jonathan Wood visited the University of Western Australia (UWA), working with Assoc/Prof. Mikhail Kostylev, Dr. Peter Metaxas and Mr. Manu Sushruth. The purpose of the trip was to carry out ferromagnetic resonance measurements in order to further his understanding in the processes involved in the change in magnetic properties he has observed at the University of Sheffield. The results found whilst there are very informative and hope to be included in publications by Jonathan in the near future. This research was made possible thanks to the Worldwide University Network (WUN) who awarded funding from the Research Mobility Programme (RMP).
Congratulations Dr Wheelwright!

Congratulations to Dr Jim Wheelwright, who successfully defended his thesis on 'Stress Based Control of Magnetic Domain Walls' in his viva on the 14th December 2015. 

Publication - Alex Mackie
Thursday, 25th February 2016
Alex Mackie recently had his first paper accepted for publication in Materials Letters. It is a brief study in collaboration with Johnson-Matthey, using Electron probe micro-analysis to see if carbon is taken into the sample during the SPS process and if so, where and how much. It is compared with a conventionally processed sample and found that there are higher levels of carbon at the surface of the SPS processed sample and to a greater depth than in the conventionally processed sample, but the levels of carbon are not thought to be significant to affect the magnetic properties.

SCAMMD @ Magnetism 2015
Sunday, 15th March 2015

In March 2015, our group visited Leeds, UK for the Magnetism 2015  conference organised by the Institute of Physics. This was an exciting opportunity for some members to present their research to the magnetism community at a conference for the first time. 

Dr. Tom Hayward presented his recent work on "Thermally-induced stochastic domain wall dynamics in Ni80Fe20 nanowires". Dr Nicola Morley, Dr Precious Shamba, Miss Ruth Bradley, Mr Tom Broomhall, Mr Alex Mackie, Mr Jonathan Wood and Mr Weigang Yang all presented posters highlighting their current research.
Congratulations also to Miss Ruth Bradley for being awarded one of the Best Student Poster prizes for her work on "Optimisation of Fe3O4 Nanostructures for Atom Trapping Applications". 
Dr Dan Allwood appointed to professorship
Friday, 30th January 2015

Congratulations to Dr Dan Allwood, promoted to Professor within the Department of Materials Science and Engineering. One of several promotions for the New Year, it is a demonstration of the commitment to academic excellence within the department and the high standard of original research on an international level.

Best Poster Prize for Matt Hodges
Thursday, 15th May 2014

Congratulations to Matt Hodges for being awarded the Best Poster prize at Intermag 2014 for his work on "Magnetic Imaging Based on Singlet Fission", describing his latest research findings regarding a class of fluorescent organic molecules that, when exposed to a magnetic field, undergo a change in fluorescence intensity.


SCAMMD @ Intermag 2014
Thursday, 15th May 2014

Intermag is one of the major conferences in magnetism and this year it was held at Dresden, Germany on 4-8th May. This year is also the 50th anniversary of the IEEE Magnetics Society, who organise and run Intermag.

Highlights of our current work were presented by Dr Tom Hayward on "Using Virtual Domain Walls to suppress Stochastic Pinning/Depinning Phenomena in Magnetic Nanowire Devices" and Dr Nicola Morley on the "Development of magnetostrictive films for MEMS sensors" and "Exploring the organic-magnetic interface for spintronic applications". Dr Matt Hodges, Dr Nicola Morley and Miss Ruth Bradley also presented posters of their work.

SCAMMD @ Magnetism 2014
Wednesday, 9th April 2014

Over the last two days our group has been in Manchester, UK attending the first of a new annual conference known as Magnetism 2014 organised by Institute of Physics. We've all been impressed with the presented research from our colleagues from across the UK and beyond and would like to thank the organisers for their part in making the conference the success it was.

Contributions from our group included two presentations from Dr Nicola Morley on the "Development of magnetostrictive films for MEMS sensors" and on "Understanding organic spin-valves". Dr Matt Hodges, Mr Khalid Omari, Miss Ruth Bradley and Dr Nicola Morley also presented posters focussing on their current research.

Congratulations Dr Negoita!
