The RASMIA Research Group focuses its research activity on the design, production and advanced characterisation of magnetic materials where magnetism is combined with other functionalities (ferroelectricity, luminescence, optical transparency, etc.) for applications in sustainable technologies: spintronics, quantum information technologies and green refrigeration. The main topic of our research is the use of Synchrotron Radiation techniques for the advanced characterisation of these materials, in which members of the group have acquired international recognition and which distinguishes us from other groups in Materials Science. This line of basic research is complemented with the development of our own technologies and their transfer to industry. To this end, we have innovated in the recovery, purification and liquefaction of helium on a small scale, with the production of a large portfolio of licensed patents and high impact results worldwide.
