A one-piece part based on magnetocaloric material comprising an alloy comprising iron and silicon and a lanthanide, comprises a base in a first plane defined by a first and second direction and N unitary blades secured to the base; the blades having a first and second dimension in the first and second direction, respectively, and a third dimension in a third direction at right angles to the first and second dimensions; an ith blade being separated from an (i+1)th blade by an ith distance; the ratio between the second dimension and first dimension being at least 10; the ratio between the third dimension and first dimension being at least 6; the first dimension being the same order of magnitude as the distance separating an ith blade from an (i+1)th blade. The magnetocaloric material can be rare-earth alloy or a composite material based on polymer binder and rare-earth alloy.

One-piece part including a magnetocaloric material including an alloy including iron and silicon and at least one lanthanide, and method for manufacturing said one-piece part

A system for metal powder atomization comprising a refractory lined melting furnace () configured to melt metal into a liquid metal bath (), in which furnace () a drain () is arranged for draining liquid metal from the bottom of the furnace. The drain () is configured to be closed by a stopping member. The system comprises an atomization chamber () configured to receive and atomize liquid metal from the melting furnace (). The system also comprises removal means controllable from the bottom region of the furnace () for removing the stopping member without interfering with the surface of the liquid metal bath (). The removal means and the stopping member are configured such that the stopping member is removable independently of the temperature of the liquid metal bath () using the removal means.
