This event at the University of Birmingham will highlight new developments across a broad range of magnetic materials. This will include soft magnets, permanent magnets, recording media, magnetocalorics, magnetic nanoparticles and measurement techniques.
As the scope of the oral session is very broad, we will have a poster session running alongside the meeting where researchers can present the more detailed findings from their work.
The event will provide a snapshot of UK research into magnetic materials in one day. Many of these research areas often run in parallel to one another and they are distinct research fields on their own. It is hoped that the meeting will provide a platform for cross fertilisation of ideas across these research topics leading to future collaboration.
Venue
The seminar is being held in Room G6 of the Metallurgy and Materials building, Building G6 in the Green zone of this pdf map. If you head for the Cafeteria marked halfway up building G6 you should see direction signs on the day.
Event Travel Information
The nearest railway station is University, and the venue is about ten minutes walk from the station. University is about ten minutes from Birmingham New Street.
Parking is difficult around the university, but the preferred car park is the multi-storey car prak between G9 and G10 in the green area on the map above. Do not park in the car park at G6 as you will be clamped.
Extending the Limits of the Sm2Co17 System – 35MGOe and Beyond
by Roger Allcock of Arnold Magnetic Technologies Ltd
From a very practical basis SmCo is needed within a range of industry sectors, from motor sport, aerospace and general industrial. In most part the high temperature properties, resistance to corrosion and non-reliance on China are desired properties. This presentation will cover the continued practical need for SmCo in such Industries and how Arnold are developing materials to fulfil such requirements
Advances in Soft Magnetic Materials
by Phil Anderson of Cardiff University Wolfson Centre
Soft ferromagnetic materials are hugely important to our increasingly electrified world and the development of new applications, new markets, and efficiency improvements demanded by legislation is driving research efforts worldwide. This presentation will examine the properties of a perfect soft magnetic material and will review research areas targeted at improving specific properties for different applications.
Some New Developments from the Magnet-Physik Magnetic Measurement Division
by Robert Hiergeist of MAGNET-PHYSIK Dr. Steingroever GmbH
In this talk a survey on some recent developments form the Magnet-Physik Dr Steingroever (MPS) magnetic measurement laboratory will be given:
(i) A novel compensated coil system that was invented by the PTB-Braunschweig [1] as a replacement for Helmholtz coil systems and was further developed in a cooperation of PTB with MPS [2]. This novel coil system consists of three pairs of coils with one pair having opposite polarity. In comparison to Helmholtz coils the magnetic field amplitude on the coil axis (z-axis) outside the coil system declines with H ∼ z^-5 significantly faster than in a Helmholtz coil (H ∼ z^-3). In addition this new coil system provides in its centre a homogeneity up to the sixth order of the magnetic field along the coil axis.
(ii) A new modified Halbach magnet system was developed consisting of identical cuboid shaped permanent magnets only. These magnets can be easily and economically manufactured, magnetized and mounted. In combination with a Helmholtz coil connected to an electronic fluxmeter the new modified Halbach magnet system is used to measure the saturation magnetic dipole moment of soft magnetic samples. Within a first prototype of the modified Halbach magnet system a flux density of 1.31 T was achieved. First measurements reveal the feasibility to analyse even weak ferromagnetic specimens.
(iii) Finally we present some recommendations for the users of our MPS PERMAGRAPH® equipment, especially for measurements at elevated temperatures up to 200 °C. We will present the effects of temperature control and distribution on material test results.

Current Metallurgical Challenges in Electrical Steels
by Cameron Pleydell-Pearce of Swansea University
The goals for improvement of transformer core and generator / motor stator / rotor electrical steel alloys are clearly defined. Moreover, previous research has clearly determined the relationships between parameters such as alloy chemistry, crystal orientation, grain size, residual stress and lamination thickness and magnetic properties such as reduced hysteresis and eddy current losses. However, the fundamental the mechanisms controlling these parameters are still an area for scientific debate. This presents significant challenges in achieving these goals from a metallurgical perspective. This presentation will broadly cover the areas of debate and use some specific examples from current research to illustrate the challenges involved.
Magnetic Materials Characterisation and Sensor Calibrations
by Stuart Harmon of NPL
What is NPL, and what is its role within the magnetics community supporting academia and industry in the UK and abroad with standardized magnetic measurements.
The presentation will cover some of NPLs work in the areas of permanent magnets, SMM and magnetic sensors.
