An optimized magnet for magnetic refrigeration [PDF]

Journal of Magnetism and Magnetic Materials, 2010
A magnet designed for use in a magnetic refrigeration device is presented. The magnet is designed by applying two general schemes for improving a magnet design to a concentric Halbach cylinder magnet design and dimensioning and segmenting this design in an optimum way followed by the construction of the actual magnet.

Sample age effect on parameters of dynamic nuclear polarization in certain difluorobenzen isomers/MC800 asphaltene suspensions

Open Chemistry, 2022
Because of magnetic spin–spin interactivity between 19F nucleus of the solvent and delocalized electrons on the MC800 asphaltene, the Overhauser dynamic nuclear polarization (DNP) method is able to give a substantial boost in the signal acquired from ...

Room temperature magnetocaloric effect of Ce0.65Mg0.35Co3

Journal of Materials Research and Technology, 2022
The magnetocaloric (MC) effect of Ce0.65Mg0.35Co3 alloy is simulated using a phenomenological model (PM). MC parameters of Ce0.65Mg0.35Co3 alloy are obtained from modelling findings as the result of simulation for magnetization vs. temperature in a 0.1 T

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

The Ising critical quantum Otto engine

New Journal of Physics, 2022
We study a four-stroke Otto engine whose working fluid is a quantum Ising chain. The thermodynamic cycle consists in sweeps of the transverse magnetic field occurring in thermal isolation, alternated by thermalisation strokes with reservoirs at different

Influence of Heat Exchanger Design on the Thermal Performance of a Domestic Wine Cooler Driven by a Magnetic Refrigeration System

Anais da Academia Brasileira de Ciências, 2022
Conventional and not-in-kind refrigerators require heat exchangers for their operation. Yet, most magnetic cooling studies do not take full account of those components despite their importance in defining the cooling capacity and temperature span.
