Review of Multi-Physics Modeling on the Active Magnetic Regenerative Refrigeration

Mathematical and Computational Applications, 2021
Compared to conventional vapor-compression refrigeration systems, magnetic refrigeration is a promising and potential alternative technology. The magnetocaloric effect (MCE) is used to produce heat and cold sources through a magnetocaloric material (MCM).

Investigation on a complex type of magnetic refrigerants for the Ericsson magnetic refrigeration.

TEION KOGAKU (Journal of Cryogenics and Superconductivity Society of Japan), 1986
A complex type of magnetic refrigerant for the Ericsson cycle has been investigated. For the magnetic refrigerant in the temperature range above -15K we have to use the ferromagnetic material, which has the internal magnetic field to arrange its spin system as far as using a magnetic field of -6T, because of increasing of the thermal excitation energy ...

Magnetic refrigeration down to 1.6 K for the future circular collider e^{+}e^{-}

Physical Review Accelerators and Beams, 2017
High-field superconducting rf cavities of the future circular collider e^{+}e^{-} may require a kW-range superfluid helium refrigeration down to 1.6 K. Magnetic refrigeration operating below 4.2 K can be an alternative to the compression/expansion helium

Magnetocaloric Effect of Two Gd-Based Frameworks

Inorganics, 2022
Magnetic refrigeration material is the key to adiabatic demagnetization refrigeration technology. In this work, two magnetic refrigerants, Gd5(C4O4)(HCOO)3(CO3)2(OH)6·2.5H2O (1) and Gd2(OH)4SO4 (2), were prepared through hydrothermal reaction.
