• ThMn12-type structure
• Ferromagnetism
• Magnetic anisotropy

A comparative study of magnetization in UFe6Al6 and LuFe6Al6, single crystals gives clear evidence for the magnetic state of uranium in UFe6Al6. Both compounds exhibit the easy-plane type of magnetic anisotropy, however, the anisotropy energy in UFe6Al6, characterized by the anisotropy constants K-1 = -7.3 MJ m(-3) and K-2 = -1.25 MJ m(-3) at 2 K, exceeds by an order of magnitude that in LuFe6Al6. Anisotropy within the easy plane in the ferromagnetic state and anisotropy in the paramagnetic range, both absent in LuFe6Al6, are observed in UFe6Al6.
