Review on magnetic refrigeration devices based on HTSC materials

International journal of refrigeration, 2019
The development of a high-efficiency magnetic refrigerating machine (magnetic refrigerator) with a superconducting magnetic field source operating in the room temperature range is currently an actual scientific and engineering problem.

Magnetic refrigerator–heat pump

Physics Today, 1979
For almost half a century low-temperature physicists have been exploiting the adiabatic demagnetization of paramagnetic materials to achieve temperatures near absolute zero. Until recently the potential utility of the magnetic cycle for refrigeration and heat pumping near room temperature has not been taken seriously for two reasons: First of all, the ...

Single molecule magnet behavior and magnetic refrigeration of four tetranuclear lanthanide (Ln = GdIII, TbIII, DyIII) clusters

New Journal of Chemistry, 2019
Four lanthanide complexes were fabricated and characterized. 1 and 4 exhibit a cryogenic magnetic refrigeration property and 3 displays slow relaxation of magnetization.

Room-temperature magnetic refrigerator using permanent magnets

IEEE Transactions on Magnetics, 2000
A magnetic refrigerator device based on adiabatic magnetic refrigeration is described. The magnetic material is cyclically magnetized and demagnetized by permanent magnets in an adiabatic process. A temperature difference of 1.6 K between the hot and cold regions was obtained under a low magnetic field (0.3 T). Gadolinium was the magnetic material used

Recent Investigations on Refrigerants for Magnetic Refrigerators

1986
In development of the magnetic refrigerator, an important problem is selection of magnetic materials as refrigerants. The main purpose of the present paper is to discuss the magnetic and thermal properties necessary for these refrigerants and to report recent investigations.
