| dc.description | U<sub>3</sub>Ni<sub>3</sub>Sn<sub>4</sub> and U<sub>2.9</sub>Ni<sub>3.0</sub>Sn<sub>3.9</sub> single crystals exhibit a non-Fermi-liquid susceptibility T<sup>-0.3</sup> between 1.7 and 10 K. The electronic heat capacity coefficient (T) of U<sub>2.9</sub>Ni<sub>3.0</sub>Sn<sub>3.9</sub> varies as the square root of temperature between 0.3 and 5 K. Although most available non-Fermi-liquid models are in disagreement with these results, the heat capacity data are consistent with a renormalization group calculation for magnetic fluctuations near an antiferromagnetic quantum critical point (QCP). Alternatively, both the magnetic and heat capacity data can be fitted to a Griffiths-phase model for magnetic clusters near a QCP, using a single characteristic exponent = 0.7. |
