Uranium compounds prepared by sputter deposition: UFe2+x

UFe2 is one of rare examples of combination of 3d and 5f magnetism in a compound with relatively high TC 162 K. U-excess is known to reduce the TC value markedly. To prepare the Laves phase with an Fe excess is much more difficult. It can be achieved by sputter deposition, but the structure becomes...

description UFe2 is one of rare examples of combination of 3d and 5f magnetism in a compound with relatively high TC 162 K. U-excess is known to reduce the TC value markedly. To prepare the Laves phase with an Fe excess is much more difficult. It can be achieved by sputter deposition, but the structure becomes amorphous. TC can increase at least to 240 K (for UFe4), but the segregation of α-Fe cannot be avoided for very high Fe concentrations.
