Abstract
Spin-lattice relaxation times ( T 1) were measured on x=0.03 and x=0.05 samples of Ce(Ru 1− x Rh x ) 2Si 2 in a temperature range between 1.5 and 60 K. Temperature dependences of T 1 in both samples do not obey the Korringa relation, and are well described by the SCR theory for an antiferromagnetic ground state. Four parameters of y 0, y 1, T 0, T A obtained by the best fitting have close values obtained by specific heat experiments. The positive y 0 value in x=0.05 means that the sample of x=0.05 has no magnetic ordering at finite temperature, which contradicts with the experimental results of neutron diffraction, specific heat and susceptibility.
