Abstract
We have demonstrated that the La(Fe,Si)13 magnetocaloric phase can be directly formed from molten on extremely slow cooling by the employment of directional solidification technique. A large amount of this magnetocaloric phase of about 85% was achieved in the as-solidified state with a cooling rate of 0.005 K/s. A large magnetic entropy change of 13.5 J/kg K under an applied field of 2 T was obtained at 202 K for the LaFe11.6Si1.4 composition without post-annealing processing.
