Magnetic refrigeration technology has attracted much attention recently due to the potential improvement in the energy efficiency and environmental benefits of traditional technology. La(FeSi) 13 magnetocaloric material, as one of the magnetocaloric materials that can be applied at room temperature, has the advantages of a high magnetocaloric effect, wide adjustable temperature zone and low cost, but it is still in the research stage due to its complex preparation method and poor durability. In this review, the development of La(FeSi) 13 magnetocaloric materials is briefly introduced, the influence of different element contents, as well as the influences of heat treatment, preparation methods and material recombination on the Curie temperature, magnetocaloric effect and hysteresis, are analysed and discussed, and the performance control methods are discussed in detail. Finally, the performance regulation method of near-room temperature La(FeSi) 13 magnetocaloric materials is summarized and prospected, and its possible future development direction is pointed out.
