Unconventional Superconductivity Near The Antiferromagnetic Criticality In Cecoin5 : A Study Of In-115-Nqr Under Pressure
PHYSICA B-CONDENSED MATTER(2005)
摘要
We report on a systematic evolution of the superconducting (SC) characteristics of CeCoIn5 via nuclear-quadrupole-resonance (NQR) measurement under pressure (P). The application of P significantly suppresses the nuclear spin-lattice relaxation rate 1/T-1 that is dominated by antiferromagnetic (AFM) spin fluctuations (SFs). The marked suppression of AFM SFs leads to the reduction in the size of SC energy gap. Nevertheless, T-c increases with the pressure due to the increase in HF bandwidth. This is expected to make the lifetime of quasi-particles sufficiently long. (c) 2005 Elsevier B.V. All rights reserved.
