“…Despite this behavior, the herein achieved pressure-dependent Δ s T maxima of 28, 28, 25, and 15 J (kg K) −1 at 0, 0.3, 0.5, and 0.8 GPa, respectively, are at approximately T > 70 K, still larger compared to the purely magnetocaloric effect of La(Fe,Si) 13 -type, ,, Fe 2 P-type, , and Mn 3 GaC , compounds, Ni(–Co)–Mn–X Heusler alloys (X = Sn, , Sb–In, Ti), and numerous highly resource critical, rare-earth containing materials. − However, it should be noted that the pressure-assisted magnetocaloric effect of the La 0.7 Ce 0.3 Fe 11.6 Si 1.4 compound is not able to surpass at approximately T < 70 K the currently best performing heavy rare-earth-based compounds. ,− This highlights also the aforementioned limitation of utilizing the first-order magnetostructural phase transition of La 0.7 Ce 0.3 Fe 11.6 Si 1.4 at such low temperatures, as minimum magnetic field changes of 4 T are required to induce the phase transition, and the hysteresis leads to irreversibility at T < 50 K (Figure (c)), thereby emphasizing the need for a tailored hysteresis to operate at such low temperatures . A graphical representation of the aforementioned comparison of Δ s T is shown in Figure S5 with additional information in Table S1.…”

The transition toward a carbon-neutral society based on renewable energies goes hand in hand with the availability of energy-efficient technologies. Magnetocaloric cooling is a very promising refrigeration technology to fulfill this role regarding cryogenic gas liquefaction. However, the current reliance on highly resource critical, heavy rare-earth-based compounds as magnetocaloric material makes global usage unsustainable. Here, we aim to mitigate this limitation through the utilization of a multicaloric cooling concept, which uses the external stimuli of isotropic pressure and magnetic field to tailor and induce magnetostructural phase transitions associated with large caloric effects. In this study, La 0.7 Ce 0.3 Fe 11.6 Si 1.4 is used as a nontoxic, lowcost, low-criticality multiferroic material to explore the potential, challenges, and peculiarities of multicaloric cryocooling, achieving maximum isothermal entropy changes up to −28 J (kg K) −1 in the temperature range from 190 K down to 30 K. Thus, the multicaloric cooling approach offers an additional degree of freedom to tailor the phase transition properties and may lead to energy-efficient and environmentally friendly gas liquefaction based on designed-for-purpose, noncritical multiferroic materials.

“…[87,88] Based on specific conditions, different gases with high economic value, such as hydrogen (H 2 liquefaction temperature is 20 K), nitrogen (N 2 , 77 K), oxygen (O 2 , 90 K), natural gas (CH 4 , 112 K at 0.1 MPa; 190 K at 4.5 MPa), propane (C 3 H 8 , 231 K), and air, can be sufficiently liquified at low temperature. [89][90][91][92][93][94][95] For example, Archipley et al report a prototype of an active magnetic regenerative refrigerator to liquefy methane with a high-field superconducting magnet, and they can successfully liquefy pure methane with their liquefier by cooling from 285 to 135 K. [93] Barclay et al investigated how a Gd-based AMR-cycle refrigerator moving through field changes of 2.7 T at 0.25 Hz was used to liquefy pure propane at two different supply pressures. [94] The EU project "HyLICAL" (2022-2027) will develop and validate a new magnetocaloric highperformance hydrogen liquefier prototype.…”

Solid‐state caloric effects as intrinsic thermal responses to different physical external stimuli (magnetic‐, uniaxial stress‐, pressure‐, and electric‐fields) can achieve a higher energy efficiency compared with traditional gas compression techniques. Among these effects, magnetocaloric energy conversion is regarded as the best available alternative and has been exploited extensively for promising application scenarios in the last decades. This review systematically introduces the magnetocaloric effect and its applications, and summarizes the corresponding representative magnetocaloric materials, as well as important progress in recent years. Specifically, the review focuses on some key understandings of the magnetocaloric effect by utilizing state‐of‐the‐art technical tools such as synchrotron X‐ray, neutron scattering, muon spin spectroscopy, positron annihilation spectroscopy, high magnetic fields, etc., and highlights their importance toward advanced materials design and development. An overview of the basic principles and applications of these advanced techniques on magnetocaloric materials is provided. Finally, the challenges and perspectives on further developments in this field are discussed. Further in‐depth understanding and manufacturing technology advancement combined with fast‐developed artificial intelligence and machine learning are expected to advance the magnetocaloric energy conversion technology closer to real applications.

Magnetocaloric hydrogen liquefaction could be a “game-changer” for liquid hydrogen industry. Although heavy rare-earth based magnetocaloric materials show strong magnetocaloric effects in the temperature range required by hydrogen liquefaction (77 ~ 20 K), the high resource criticality of the heavy rare-earth elements is a major obstacle for upscaling this emerging liquefaction technology. In contrast, the higher abundances of the light rare-earth elements make their alloys highly appealing for magnetocaloric hydrogen liquefaction. Via a mean-field approach, it is demonstrated that tuning the Curie temperature (TC) of an idealized light rare-earth based magnetocaloric material towards lower cryogenic temperatures leads to larger maximum magnetic and adiabatic temperature changes (ΔST and ΔTad). Especially in the vicinity of the condensation point of hydrogen (20 K), ΔST and ΔTad of the optimized light rare-earth based material are predicted to show significantly large values. Following the mean-field approach and taking the chemical and physical similarities of the light rare-earth elements into consideration, a method of designing light rare-earth intermetallic compounds for hydrogen liquefaction is used: tunning TC of a rare-earth alloy to approach 20 K by mixing light rare-earth elements with different de Gennes factors. By mixing Nd and Pr in Laves phase (Nd,Pr)Al2, and Pr and Ce in Laves phase (Pr, Ce)Al2, a fully light rare-earth intermetallic series with large magnetocaloric effects covering the temperature range required by hydrogen liquefaction is developed, demonstrating a competitive maximum effect compared to the heavy rare-earth compound DyAl2.
