“…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.

“…It is also a key issue to find an ideal ambient temperature refrigerant material for magnetic refrigeration research [1][2][3][4]. Compound LaFe 13−x Si x has served as a potential room temperature magnetic refrigeration material because of its high magnetocaloric effect, low cost and environment-friendly property [5][6][7][8]. LaFe 13−x Si x with a low Si content (x ≤ 1.6) has become the focus of this kind of compounds because of its large magnetic volume effect and the characteristic of itinerant electron magnetic transition above the Curie temperature T C [9][10][11][12].…”

The arc-melting method was adopted to prepare the compound La0.5Pr0.5(Fe1−xCox)11.4Si1.6 (x = 0, 0.02, 0.04, 0.06, 0.08), and the magnetocaloric effect of the compound was investigated. As indicated by the powder X-ray diffraction (XRD) results, after receiving 7-day high temperature annealing at 1373 K, all the compounds formed a single-phase cubic NaZn13 crystal structure. As indicated by the magnetic measurement, the most significant magnetic entropy change |∆SM(T)| of the sample decreased from 28.92 J/kg·K to 4.22 J/kg·K with the increase of the Co content under the 0–1.5 T magnetic field, while the Curie temperature TC increased from 185 K to the room temperature 296 K, which indicated that this series of alloys are the room temperature magnetic refrigerant material with practical value. By using the ferromagnetic Curie temperature theory and analyzing the effect of Co doping on the exchange integral of these alloys, the mechanism that the Curie temperature of La0.5Pr0.5(Fe1−xCox)11.4Si1.6 and La0.8Ce0.2(Fe1−xCox)11.4Si1.6 increased with the increase in the Co content was reasonably explained. Accordingly, this paper can provide a theoretical reference for subsequent studies.

“…Magnetic refrigeration could drastically reduce CO2 emission by the cooling sector through reduced electricity consumption, due to the potential high energy efficiency of this technology [1,2]. A key challenge in its commercialisation arises from the poor mechanical stability of the La(Fe,Mn,Si)13 magnetocaloric materials when subjected to simultaneous action of several generalised forces during processing and service, leading to limited lifetime [3,4]. Understanding the mechanical properties of these materials is therefore of high demand, yet studies are limited [5,6].…”
