Thermodynamics of magnetic refrigeration
International Journal of Refrigeration, 2006A comprehensive treatment of the thermodynamics of cyclic magnetic refrigeration processes is presented. It starts with a review of the work, heat and internal energy of a magnetized specimen in a magnetic field, and a list of the thermodynamic potentials is given. These are based on the very recent discovery of an alternative Kelvin force. It is shown

Nanocomposites For magnetic Refrigeration
MRS Proceedings, 1992ABSTRACTUpon the application of an external magnetic field, the magnetic spins in a material partially align with the field, thereby reducing the magnetic entropy of the spin system. When performed adiabatically, the specimen's temperature will rise.

Cryogenics (Guildford), 2019
A hybrid cryogenic refrigerator that combines the magnetic refrigeration effect with the GM refrigeration effect has been experimentally studied. ErNi and TmCuAl, which have large magnetocaloric effects, are used to fill the second (low-temperature ...

Magnetic refrigeration—towards room-temperature applications
Physica B: Condensed Matter, 2003Modern society relies very much on readily available cooling. Magnetic refrigeration based on the magneto-caloric effect (MCE) has become a promising competitive technology for the conventional gas-compression/expansion technique in use today. Recently, there have been two breakthroughs in magnetic-refrigeration research: one is that American ...

Coordination‐Cluster‐Based Molecular Magnetic Refrigerants
The Chemical Record, 2016AbstractCoordination polymers serving as molecular magnetic refrigerants have been attracting great interest. In particular, coordination cluster compounds that demonstrate their apparent advantages on cryogenic magnetic refrigerants have attracted more attention in the last five years.

Synthesis, structures and magnetic refrigeration properties of four dinuclear gadolinium compounds
Polyhedron, 2019Four new Gd2 compounds, [Gd2(L1)2(acac)2(CH3O)2] (1), [Gd2(L1)2(beac)2(OH)2] (2), [Gd2(L2)2(C4H10O3)2(CH3OH)2] (3) and [Gd2(L3)2(acac)2(CH3O)2] (4), were synthesized by solvent evaporation methods and studied by structural analyses and magnetic analyses.

Journal of Applied Physics, 1987
A complex new magnetic refrigerant, suitable for the ideal Ericsson cycle, has been investigated. Above ∼15 K it is necessary to use ferromagnets as a magnetic refrigerant. However, temperature variation for the magnetic entropy change in a homogeneous ferromagnet is not suitable for the Ericsson cycle.
