Abstract	Flake-like LaFe_11.8-xCo_xSi_1.2 alloys were successfully prepared in kilogram quantities by a strip-casting technique. It is found that a large amount of NaZn₁₃-type La(Fe,Co,Si)₁₃ phase (above 95 vol.%) can form in LaFe₁₁Co_0.8Si_1.2 strip-cast flakes annealed at 1323 K for 24 h. The resulting alloy exhibits a maximum entropy change of 8.4 J/kg K and negligible magnetic hysteresis under a field change of 0-2 T. In addition, the Curie temperature can be accurately tuned by adjusting the concentration ratio of the Fe/Co. Our results indicate that the strip casting is an effective way to produce high-performance La(Fe,Co,Si)₁₃ materials for room-temperature magnetic cooling.
