Samarium Wikipedia
Samarium is a chemical element with the symbol Sm and atomic number 62. It is a moderately hard silvery metal that slowly oxidizes in air. Being a typical member of the lanthanide series, samarium usually assumes the oxidation state +3. Compounds of samarium(II) are also known, most notably the monoxide SmO, monochalcogenides SmS, SmSe and SmTe, as well as samarium(II) iodide.
[Aimants] Néodyme ? Samarium ? Cobalt ? Acide
Aimants souples, déchirables à la main ? Ne cherche plus, le seul cobalt que tu y trouveras c'est les additifs du caoutchouc qui sert de matrice à de la ferrite. Et pour le coup, c'était sur qu'il y avait du FeCl3 mais maintenant pour ce type d'aimant je pense que tu ne trouveras rien d'autre.
