Measurements on URu{sub 2-x}Re{sub x}Si{sub 2} single crystals indicate that substitution of Re for Ru in URu{sub 2}Si{sub 2} reduces the transition temperature of the hidden order state and quickly destroys superconductivity. At intermediate Re concentrations, weak ferromagnetism emerges and non Fermi liquid (NFL) behavior is observed in the low-temperature specific heat and electrical resistivity. A scaled Arrott analysis of the magnetization indicates the onset of ferromagnetism at x = 0.15, where the hidden order disappears, and that the quantum phase transition is associated with novel critical exponents.
