Abstract:
A permanent magnet comprising an antiferromagnetic layer and a ferromagnetic layer having a first sub-layer made of a first type of ferromagnetic material, the first type of ferromagnetic material being an at least partially crystallized alloy of iron and cobalt, and a second sub-layer made of a second type of ferromagnetic material, this second type of ferromagnetic material also being an alloy of iron and cobalt in which the proportion of face-centered cubic crystals is less than the proportion of face-centered cubic crystals in the first type of ferromagnetic material.
