Magnetic refrigeration using the adiabatic demagnetization of paramagnetic materials was the first method to achieve temperatures below 1 K back in 1933. This method is still used in solid-state physics to achieve very low temperatures, although currently one uses mostly liquid helium as a coolant in the region close to 1 K.

However, there are currently several reasons to revive magnetic refrigeration. On the one hand, magnetic refrigeration remains the preferred method for space applications and is one of the options for cooling the superconducting magnets of the Future Circular Collider. On the other hand, there are ideas how to improve magnetic refrigerants by using cooperative effects, such as the quantum phase transitions induced by a magnetic field and geometric frustration

The purpose of the workshop is a meeting of French and European experts to identify the perspectives for future research and applications at the European level
