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 Dr Weigang Yang who successfully defended his thesis on 'Electric Field Control of Magnetic Properties in Multiferroic Heterostructures' in his viva on the 21st April 2016
On the 4th-5th April, SCAMMD attended Magnetism 2016 organised by the Institute of Physics.
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 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.
From the 11th-15th January, Professor Dan Allwood, Dr Tom Hayward and Alex Mackie from SCAMMD attended the MMM/Intermag joint conference in San Diego. The following research from members of SCAMMD was presented:
Influence of non-magnetic phases on the magnetic properties of high-resistivity composite rare-earth permanent magnets.
A.J. Mackie , J. Dean and R. Goodall
Microstructural Dependence of Sintered Nd-Fe-B Permanent Magnet Properties.
G. Fadhil , M. Hodges , A. Rana , W.M. Rainforth , A. Thomas , A.C. Urda , J. Dean and D. Allwood
Ballistic Rectification of Vortex Domain Wall Chirality at Nanowire Corners.
K.A. Omari , R. Bradley , T.J. Broomhall , M. Hodges , M.C. Rosamond, M. Im, P. Fischer and T.J. Hayward

Alex Mackie has blogged about his first experience representing SCAMMD at an international conference, which can be found at https://materialsatsheffield.wordpress.com/2016/01/13/my-first-international-conference-magnetism-2016/
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.
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.

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.
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.
