Low-dimensional MAgnetoCalorics for Efficient Refrigeration - Low-MACER

Project summary

• Rationale Cryogenic cooling is key for many applications, as medical sensing, quantum technologies or H2 liquefaction. It relies on gas compression (inefficient, costly, and maybe harmful). Magnetic refrigeration is a powerful alternative. • Objectives Low-MACER will exploit the magnetocaloric effect (MCE) to store/release a large entropy by scanning a magnetic field. Low-dimensional and metamagnetic materials will boost the MCE in the desired temperature range using low fields. • Potential applications Combining theory and experiment, we will prepare new MC materials for magnetic refrigeration and thermal storage. We will focus on the 20 K region, relevant to the H2 liquefaction in green-energy applications. • Impact and potential benefits Our new "sustainable advanced materials for energy" will have expected impact on the scientific (knowledge generation & dissemination), economic (refrigeration industry), social (health, energy market), and environmental (green energy) dimensions.
