“…It was found that the presence of a corrosion inhibitor is crucial to maintain the chemical stability of the magnetocaloric materials. 46 A magnetic field was also found to influence the chemical stability of La(Fe, Si) 13 alloys immersed in deionized water�the direction of the magnetic field played a critical role in the corrosion rate. 47 For example, the sample immersed in deionized water for 3 days with exposure to 1 T parallel and 1 T perpendicular magnetic fields experienced a 56 and 22% reduction in its corrosion rate when compared to the case with zero magnetic field.…”

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.
