Abstract
U3Ni3Sn4 and U2.9Ni3.0Sn3.9 single crystals exhibit a non-Fermi liquid susc eptibility chi proportional to T-0.3 below 10 K. The electronic heat capaci ty coefficient gamma(T) of U2.9Ni3.0Sn3.9 varies as the square root of temp erature between 0.3 and 5 K, consistent with fluctuations near an antiferro magnetic quantum critical point.
