Investigation of the Magnetic Refrigerant for the Ericsson Magnetic Refrigerator
Japanese Journal of Applied Physics, 1987In the temperature range above ∼20 K, the Ericsson magnetic refrigeration cycle has to be adopted instead of the Carnot cycle, because the lattice entropy becomes no longer negligible as compared with the magnetic entropy. Moreover, in this range since the thermal agitation energy ∼kT of spin also increases, the ferromagnetic materials have to be ...

Magnetic refrigeration with GdN by Active Magnetic Refrigerator cycle
MRS Proceedings, 2011ABSTRACTA magnetic refrigeration test was performed using a test device filled with spherical GdN material synthesized by the hot isostatic pressing (HIP) method. Refrigeration with an active magnetic regenerator cycle was tested in the temperature range between 48 and 66 K, with the field changing from 1.2 to 3.7 T and 2.0 to 4.0 T at upper and lower ...

Refrigerator Magnet Investigation
The Physics Teacher, 2023Refrigerator magnets belong to a group of simple devices that we use all the time but rarely question how they work. While refrigerator magnets have received considerable attention in physics education literature, the focus of these papers was mainly on the explanations of their structure or demonstrations of the structure of the magnetic layer.

Magnetic nanocomposites for magnetic refrigeration
Nanostructured Materials, 1993Enhanced magnetocaloric effects have been predicted to occur in composite materials possessing magnetic species which have been reduced to nanometer-sized dimensions. Convincing experimental evidence is first presented here verifying these predictions. A new type of magnetic nanocomposite, one which is a single crystallographic phase, is also reported ...

GeoThermag: A geothermal magnetic refrigerator
International Journal of Refrigeration, 2015Abstract Magnetic refrigeration has played an important role in the scientific landscape in recent years and could potentially be an alternative to vapour compression technology. Although new prototypes have recently been developed and new material refrigerants have been tested, there is still no equipment that can be used in the refrigeration ...

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.
