Augmenting refrigerator magnets
Proceedings of the 4th Nordic conference on Human-computer interaction: changing roles, 2006In this paper we present a number of augmented refrigerator magnet concepts. The concepts are shown to be derived from previous research into the everyday use of fridge surfaces. Three broadly encompassing practices have been addressed through the concepts: (i) organization/planning in households; (ii) reminding; and (iii) methods household members use

Recent Investigations on Refrigerants for Magnetic Refrigerators
1986In 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.

Investigating refrigerator magnets
The Physics Teacher, 2000Two articles recently carried in The Physics Teacher have included discussions of “refrigerator magnets.” These articles have been informative, and I would like to add the simple analogy of a horseshoe magnet to the discussion. After all, a horseshoe magnet is a “one-sided” magnet in that it has the effective part of its field only on the end where the

A parasitic magnetic refrigerator for cooling superconducting magnet
IEEE Transactions on Magnetics, 1988Experimental results are presented for a practical magnetic refrigerator equipped with a large-field racetrack superconducting magnet, an auxiliary GM (Gifford-McMahon) refrigerator, and a liquid-helium vessel for magnetic refrigeration cooling. In this design the magnetic refrigerator is equipped with 14 pieces of GGG (gadolinium-gallium-garnet ...

1994
The demand for ways to reliably estimate the expected efficiency and power density of magnetic refrigerators led in past years to increasing efforts to develop computational models and numerical simulation of magnetic refrigeration processes. Such methods, in addition, provide a better understanding of the loss mechanisms in magnetic refrigerators and ...

Magnetic refrigeration: Application and enabler for HTSC magnets
AIP Conference Proceedings, 1992Magnetic refrigeration is potentially a highly efficient and high power density technology because the magnetization process on which it is based is essentially reversible and the volumetric heat capacity of the refrigerant is very high. Large magnetic fields produced by superconducting magnets are needed to most effectively couple to the magnetic ...

Magnetic Materials for Magnetic Refrigeration
Magnetocaloric materials serve as the cornerstone of magnetic refrigeration technology, which emerges as a compelling and globally sustainable alternative to conventional vapor-compression-based cooling systems. Unlike traditional methods that rely on mechanical compression, magnetic refrigeration operates through magnetization and demagnetization ...openaire +1 more source
Refrigeration Capacity of a GM Refrigerator with Magnetic Regenerator Materials
1996An investigation was made of the refrigeration capacity of a two-stage Gifford-McMahon (GM) refrigerator using a layer structural regenerator (multilayer regenerator) with magnetic regenerator materials.

Magnetic and Thermal Properties of Dy3Al5O12 as a Magnetic Refrigerant
1986We investigated the magnetic entropy of Dy3AlsO12 (DAG), which is one of the most promising refrigerants for the Carnot-type magnetic refrigerator. In the present investigation we measured the specific heat in zero magnetic field and the magnetization as a function of temperature and magnetic field, and from the analysis of these experimental results ...
