To verify effectiveness for a magnetic refrigerant, we have fabricated spheres of La(Fe0.86Si0.14)13 by a rotating electrode process (REP). The Curie temperature of the spheres was increased up to around room temperature by hydrogen absorption. Putting these spheres into an active magnetic regenerator (AMR) test module, the temperature span of 16 K in the vicinity of room temperature was obtained in a steady state. Consequently, it has been confirmed for the first time that the La(Fe0.86Si0.14)13 spheres perform as an excellent material for the AMR.
