摘要：

We have performed nuclear quadrupole resonance (NQR) measurements on In-115 nuclei of Ce2CoIn8. Spin-lattice relaxation rate 1/T-1 remains nearly constant at high temperatures. With decreasing temperature T, 1/T-1 decreases and is proportional to T above T-SC. 1/T-1 of Ce2CoIn8 is quite similar to that of pressurized CeIn3 at about 2.7 GPa. The sign of superconductivity was observed at around OAK. (c) 2005 Elsevier B.V. All rights reserved.
