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
New Group Member - Mr. Patrick Pan joins FMM!
Monday, 25th September 2017

On the 25th September 2017, a new member has joined the FMM (Function Materials - Magnetics) research group! 

Mr Patrick Pan will be starting his 3 - 4 years PhD project where his research topic is: Remote Magnetic Monitoring of Swelling in Intermediate Level Waste Canisters. The project will be supervised by Dr Claire Corkhill and Dr Tom Hayward.

His project is funded by the Nuclear Decommissioning Authority (NDA) Bursary Scheme organised by the National Nuclear Laboratory (NNL).
Congratulations Dr Yang

SCAMMD @ Magnetism 2016
Wednesday, 13th April 2016

On the 4th-5th April, SCAMMD attended Magnetism 2016  organised by the Institute of Physics

Dr. Tom Hayward presented his work on "Manipulating domain walls with surface acoustic waves" and Dr Precious Shamba presented her work on "Tuning phase transitions and the magnetocaloric effect of La(Fe,Si)13 alloys", Miss Ruth Bradley, Mr Tom Broomhall, Mr Qayes Al-dulaim, Mr Ghaiath Fadhil, Mr Alex Wynn, Mr Alex Mackie, Mr Jonathan Wood and Mr Weigang Yang all presented posters highlighting their current research.
Congratulations are in order for Alex Mackie for being awarded one of the Best Student Poster prizes for his work on "Sm2(Co,Fe,Cu,Zr)z and CaF2 composite permanent magnets processed by Spark Plasma Sintering". 
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".
