A series od UFe_{2+x} materials was prepared using splat cooling. The Laves phase structure can accommodate up to 0.3 Fe excess, while T_C is enhanced from 172 K to approximately 240 K. Higher Fe concentration leads to the segregation of α-Fe. ^{57}Fe Mössbauer spectroscopy indicates higher Fe magnetic hyperfine fields on Fe nuclei occupying the U sublattice than for the regular Fe sites.
