N2 - The results of low-temperature ac susceptibility, dc magnetization, magnetic relaxation, specific heat, and electrical resistivity measurements on the uranium intermetallic compound UCuSi, a hexagonal CeCd2-type non-magnetic atom disorder system, are reported. The results establish that a spin-glass state is formed in this compound at low temperature. Some dynamical parameters characterizing the spin freezing state of this system, such as static spin freezing temperature Ts, critical exponent zν, and activation energy Ea, are determined from dynamical analysis of the ac susceptibility data. The observed properties are discussed based on a magnetic cluster model.
