“…(3) light elements, such as N, H, B, and C, functioning as interstitial atoms. 102 The characteristics of magnetocaloric La(Fe,Si) 13 alloys have been 73 improved using a number of methods, including partial element replacement, atom insertion, and provision of additional pressure through hydrogenation. 64 The substantial entropy shift in LaFeSi hydrides may be adjusted according to the hydrogen concentration, and because the itinerant-electron meta magnetic transition is weaker after hydrogenation, both thermal and magnetic hysteresis are noticeably decreased.…”

“…Magnetic refrigeration, which is based on the magnetocaloric effect (MCE), shows a lot of potential for competing with the conventional vapor-compression cooling method in terms of being an ecologically friendly and energy-efficient cooling technique. However, the utilization of this category of alloys in certain settings has a number of challenges that must be overcome . It is difficult to acquire directly from ordinary solidification processes normalγ‐ Fe + La → La false( Fe , Si false) 13 ( τ 1 a ) which frequently leads in a mixed microstructure of normalα‐ Fe + La false( Fe , Si false) 13 ( τ 1 a ) + LaFeSi ( τ 4 ) where the NaZn 13 -type structure in the pseudobinary LaFe 13– x Si x compounds is metastable around ambient temperature.…”

Energy-efficient refrigeration technology needs to advance ineluctably due to rising energy consumption and diminishing fossil fuel and primitive hydrocarbon reserves. Further, the existing gas compression method releases huge amount of chlorofluorocarbons (CFCs) that deplete the ozone layer. This is a global concern, which demands an immediate remedial technology. As a potential solution to the problem of sustainability and a means of meeting the everincreasing demand for energy, environmentally friendly and socially responsible renewable energy sources could serve as an ideal replacement for traditional refrigeration technology. Solid-state refrigeration using magnetocaloric materials is one prominent technique that can be adopted for clean and economical refrigeration or cooling requirements. In this review, we briefly introduce the present understanding on magnetocaloric LaFe 13−x Si x alloys with a specific emphasis on their application in magnetic refrigeration. This paper deals with the advantages and disadvantages of different synthesis methods for producing LaFe 13−x Si x and enhancing its magnetocaloric effects. Annealing time, yield, composition, and relative cooling power are examined as prospective industrial implementation factors for the La(Fe,Si) 13 synthesis process. The initial sections have been devoted to an overview of the magnetocaloric effect and its different types and history. Further, the article reviews the evolution of a new preparation method called melt spinning, other synthesizing methods, and some developments around the world for the prototypes of La(Fe,Si)-based magnetic refrigeration methods. According to the findings in the scholarly literature, the synthesis process of melt spinning has the potential to be commercialized because of its capacity to create huge quantities of La(Fe,Si) 13 with a high purity in a very short amount of time.

Rare‐earth‐based high‐entropy alloys (HEAs) with large magnetocaloric effect (MCE) have been recently recognized as good candidates for magnetic refrigeration. Herein, the complex magnetic transition, MCE, refrigerant capacity (RC), and magnetic‐phase diagram of single‐phase TbDyHoEr HEA are studied. It is showed in the results that due to complex magnetic transition and an ideal table‐like MCE, the RC of TbDyHoEr is significantly improved from 883.19 to 1049.22 J kg−1 by melt‐spun treatment. In terms of RC value and hysteresis performance, the melt‐spun treatment significantly improves the application potential of TbDyHoEr HEA as a high‐efficient magnetic refrigeration material, and the ideal table‐like MCE in a large temperature range enables this material to meet the requirements of both cryogenic refrigeration and mesothermal refrigeration for an Ericsson cycle.

“…La(Fe,Si) 13 represents a promising magnetocaloric material owing to its low material cost, better adiabatic temperature change and isothermal entropy change, and the possibility to tune its Curie temperature depending on the applications. − Preparation of the La(Fe,Si) 13 alloy family with a single NaZn 13 phase is challenging. , Certain manufacturing processes require the addition of excess La, which is subsequently removed. , Depending on the degree of removal, it results in an alloy with insufficient or excess La, leading to, among others, the formation of the α-Fe phase. − It also affects the magnetic entropy change, either favorably or unfavorably. − Improvements are needed in the mechanical stability of the La(Fe,Si) 13 alloy family, which is the focus of several studies. ,− …”

Magnetic refrigeration (MR) is a cutting-edge technology that promises high energy efficiency and eco-friendliness, making it an exciting alternative to traditional refrigeration systems. However, the main challenge to its widespread adoption is cost competitiveness. In this context, the use of liquid metals as heat transfer liquids in the MR has been proposed as a game-changing solution. Unfortunately, the toxicity and flammability of these liquid metals have raised serious concerns, limiting their practical use. In this study, we investigate the compatibility of a nontoxic and nonflammable GaInSn-based liquid metal with a magnetocaloric material, La(Fe,Mn,Si) 13 H z , over a 1.5 year period. Our findings reveal nearly a 14% reduction in specific cooling energy and peak-specific isothermal magnetic entropy change for the considered magnetocaloric material. Our study provides valuable insights into the long-term stability of magnetocaloric materials and their compatibility with liquid metals, facilitating the development of more cost-effective and sustainable MR systems.
