Abstract

U₃Ni₃Sn₄ and U_2.9Ni_3.0Sn_3.9 single crystals exhibit a non-Fermi liquid susceptibility χ ∝ T^-0.3 below 10K. The electronic heat capacity coefficient γ(T) of U_2.9Ni_3.0Sn_3.9 varies as the square root of temperature between 0.3 and 5 K, consistent with fluctuations near an antiferromagnetic quantum critical point.
