Research summary

The magnetic material gadolinium-silicon-germanium shows an extremely large change in temperature when magnetized. This material has great potential for use in high efficiency, environmentally friendly magnetic refrigerators. The work undertaken in this project aims to understand better the reasons for this unusual behaviour in the material, and from this to open up opportunities for discovery of other materials with similarly high potential for magnetic refrigeration. If refrigerators based on these magnetic materials are introduced into the market then it will result in much less waste of energy in refrigerators, and much less problems from damage to the ozone layer caused by chloro/fluoro carbons used in conventional refrigerators.
