| Description | The functional performance of magnetic materials is heavily dependent on many factors, some of the more crucial being composition, microstructure and temperature of application. Understanding the complex balance of these factors is critical and PRETAMAG uses a combination of computational modelling, synthesis and characterisation measurements to investigate the underlying physics within these magnetic materials. Comparison between modelling and physical measurements is of key interest and one such way this has been done is by studying these materials at high temperature. Samples fabricated at the University of Warwick were measured at the University of Birmingham to determine the magnetic properties at high temperatures. Correlating these measurements against modelling results show good agreement between the two methods of study, confirming that the use of modelling alongside synthesis and testing is a driver to optimising the future development of these materials. |

| Title | Anomalous small-angle X-ray scattering of alloys |
| Description | Anomalous small-angle X-ray scattering (ASAXS) involves scanning the X-ray energy through the absorption edges of the target elements. This is a powerful but so-far little used technique. We have carried out a preliminary study in the context of this research project at the I22 beamline (Diamond light source). |
