## Description

- description: Magnetic refrigeration systems are widely recognized as efficient,
    compact, and environmentally friendly, given their trivial effect on ozone-depleting
    or greenhouse gases (e.g., CFCs, HFCs, and HFOs). After the success of liquefying
    hydrogen by Sir James Dewar in the late 19th century, several liquefaction technologies
    have been developed. Conventional liquefaction systems involve Joule–Thomson and
    turbine expansion systems. However, those systems are energy-intensive, which
    entails about 10–20 kWh/kg for H₂ liquefaction. Magnetic refrigeration systems
    have recently been employed as a potential alternative to conventional liquefaction
    systems. Magnetic refrigeration relies on the magnetocaloric effect (MCE), whereby
    the temperature of a magnetic material changes in response to variations in the
    magnetic field [1]. This study targets examining different magnetocaloric materials
    for H₂ liquefaction.
