摘要: We present a simple hot press-based method for processing La(Fe,Si)$_{13}$-based compounds consisting of La-Fe-Co-Si-C particles and phenolic resin. The magnetic entropy change $\Delta S$ per unit mass for the LaFe$_{10.87}$Co$_{0.63}$Si$_{1.5}$C$_{0.2}$/phenolic resin compounds have nearly the same magnitude with the base materials. With the content of phenolic resin of 5.0 wt%, the compound conductivity is 3.13 W$\cdot$m$^{-1}\cdot$K$^{-1}$. In order to measure the cooling performance of La(Fe,Si)$_{13}$-based compounds, the La(Fe$_{11.6-x}$Co$_{x}$)Si$_{1.4}$C$_{0.15}$ ($x=$0.60, 0.65, 0.75, 0.80, 0.85)/phenolic resin compounds were pressed into thin plates and tested in a hybrid refrigerator that combines the active magnetic refrigeration effect with the Stirling cycle refrigeration effect. The test results showed that a maximum cooling power of 41 W was achieved over a temperature span of 30 K.
