Abstract

The invention is related to a nuclear-demagnetization refrigerator (1) comprising: • a refrigerant (2) made of a superconducting magnetocaloric material; • a main coil (5); • at least a first heat switch (3) thermally coupled to the refrigerant (2), comprising: • a channel piece (31) made of the same superconducting magnetocaloric material as the refrigerant; and • a magnetic device (32), such as a coil, distinct from the main coil, configured to apply a magnetic field on the channel piece (31) that is greater than the critical magnetic field of the superconducting magnetocaloric material.
