title = "Short-range magnetic correlations in the highly correlated electron compound CeCu4Ga",
abstract = "We present experimental results for the heavy-electron compound CeCu4Ga which show that it possesses short-range magnetic correlations down to a temperature of T=0.1 K. Our neutron scattering data show no evidence of long-range magnetic order occurring despite a peak in the specific heat at T∗=1.2 K. Rather, magnetic diffuse scattering occurs which corresponds to short-range magnetic correlations occurring across two unit cells. The specific heat remains large as T∼0 K, resulting in a Sommerfeld coefficient of γ0=1.44(2) J/mol K2, and, below T∗, the resistivity follows T2behavior and the ac magnetic susceptibility becomes temperature independent. A magnetic peak centered at an energy transfer of Ec=0.24(1) meV is seen in inelastic neutron scattering data which shifts to higher energies and broadens under a magnetic field. We discuss the coexistence of large specific heat, magnetic fluctuations, and short-range magnetic correlations at low temperatures and compare our results to those for materials possessing spin-liquid behavior.",
