Description

Ce2CoIn8 is a superconductor with TSC=0.4K and Ce2RhIn8 is an antiferromagnet with TN=2.8K. Ce2RhIn8 becomes superconducting below 1.4K at 2.0GPa. Their crystal structure can be viewed as the successive layers of the heavy fermion compounds CeTIn5 and CeIn3. In this study, we have performed nuclear quadrupole resonance (NQR) measurement on 115In nuclei of Ce2TIn8. Spin-lattice relaxation rate 1/T1 of Ce2CoIn8 decreases with decreasing temperature T and is proportional to T just above TSC. This is contrast with the T1/2 dependence of the 1/T1 of pressurized Ce2RhIn8 at low temperatures
