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

Congratulations to Jonathan Wood and Professor Allwood for the publication of their paper on "Control of ferromagnetic properties of Ni80Fe20 thin films by voltage-induced oxidation" in Journal of Applied Physics. Further reading of this article can be found here

Graduation Celebrations!
Tuesday, 17th July 2018

Congratulations to both Dr Ruth Bradley and Dr Ghaiath Fadhil who both graduated not only from our group, but also the university today.

With the lovely weather and very resplendant attire, we are proud of both of them for what they have achieved.

We wish them all of the best in the future.

SCAMMD research at OFFSPEC, ISIS
Monday, 4th June 2018

SCAMMD members Professor Dan Allwood, Dr Tom Hayward and Richard Dawidek went to OFFSPEC at the ISIS Neutron Source, Rutherford Appleton Laboratory, Didcot from the 11th-18th May. Experiments investigating magnetic nanoring arrays with Polarised Neutron Reflectometry (PNR) took place over the course of the visit.

We thank Dr Nina-Juliane Steinke and Dr Jos Cooper for their help and collaboration during our time there.

SCAMMD @ Magnetism 2018
Friday, 20th April 2018

On the 9th-10th April, Functional Materials - Magnetics Group (SCAMMD) attended Magnetism 2018  organised by the Institute of Physics

Mr Tom Broomhall got the chance to present his work on "Magnetism you can rely on: A materials-science based solution to stochastic domain wall pinning in magnetic nanowire devices" to the Magnetism Community. Other members of the group; Dr. Tom Hayward, Mr Alaa Alasadi, Mr Qayes Aldulaim, Mrs Saturi Baco, Mr Richard Dawidek and Mr Patrick Pan all presented posters highlighting their current research.
 
Although nobody in the group won the Best Student Poster prize everyone had an enjoyable time learning from other academic staffs on the most up-to-date research that is happening in the UK. 
 
 
 
Congratulations Dr Fadhil!
Friday, 2nd March 2018

Congratulations to Dr Ghaiath A. Fadhil from the Functional Materials - Magnetics group, who successfully defended his thesis of:

"The role of microstructure on the performance of sintered Nd-Fe-B magnets"

on the 6th November, 2017 with minor corrections! 

The thesis can be read online at http://etheses.whiterose.ac.uk/18936/ after the 8th December 2018.

Please get in contact with the group if you'd like to request a copy before then. 

New publication from Alaa Alasadi
Monday, 5th February 2018

Alaa Alasadi, Frederik Claeyssens and Dan Allwood published a paper (Laser direct writing (LDW) of magnetic structures) on AIP Advances. Further reading of this article can be found here.

Dr K. A. Omari and T. J. Hayward have published a paper on "A Micromagnetic Protocol for Qualitatively Predicting Stochastic Domain Wall Pinning" in Scientific Reports - Nature! Further reading of this article can be found here.

FMM @ ICISM 2017
Friday, 15th December 2017

Congratulations to Professor Allwood who was the keynote speaker at the International Conference on Innovative and Smart Materials (ICISM) 2017, held in Paris from the 11th December to the 13th.

 

Professor Allwood presented a number of areas of the Functional Materials - Magnetics group relating to his areas of expertise in patterned ferromagnetic nanorings. These included hybrid multi-ferroic systems for controlling domain wall position using applied stress and the nature of domain wall propagation in an array of overlapping NiFe nanorings. 

Congratulations to Mr T. J. Broomhall and T. J. Hayward having published a paper on "Suppression of Stochastic Domain Wall Pinning Through Control of Gilbert Damping" in Scientific Reports - Nature! Further reading of this article can be found here.

MMM 2017
Tuesday, 14th November 2017

​From the 7th - 10th November, 3 representatives from the Functional Materials - Magnetics Group attended the Magnetism and Magnetic Materials (MMM) 2017 conference in Pittsburgh, USA. 

Professor Dan Allwood presented a poster "Stress Induced Anisotropy in Ni Nanorings" on Tuesday  in the Structured Materials session. 

Richard Dawidek and Alaa Al-Asadi presented talks on Friday 10th in session HC on Artificial Spin Systems. These were respectively titled: "Emergent Behaviour in Interconnected Nanoring Arrays" and "Laser Direct Writing (LDW) of Magnetic Structures" 

All thoroughly enjoyed the visit to Pittsburgh and the opportunity to showcase the research carried out in Sheffield to an international audience
