Abstract: The invention relates to a one-piece part containing at least one magnetocaloric material including an alloy including iron and silicon and at least one lanthanide, characterized in that: said part comprises a base located in a first plane defined by a first direction (Dx) and a second direction (Dy), and a set of N unit blades (La,i) rigidly connected to said base; said blades have a first dimension (D Lai, x) in the first direction, a second dimension (D
Lai ,y) in the second direction and a third dimension (D
Lai ,,) in a third direction (Dz) perpendicular to the first and second directions; an i
th blade is separated from a (i+1)
th blade by an i
th distance (di); the ratio between the second dimension and the first dimension is great than or equal to 10; the ratio between the third dimension and the first dimension is greater than or equal to 6; and the first dimension is of the same order of magnitude as the distance between an i
th blade and a (i+1)
th blade. The magnetocaloric material may be a rare earth alloy or a composite material containing a polymer binder and a rare earth alloy. The invention also relates to an extrusion method for producing the one-piece parts of the invention.
