Abstract

The nuclear spin relaxation rate between T=0.09 and 100K in a new heavy fermion (HF) compound was presented. The new HF compound was found to be more itinerant than known Cerium based HFs from the nuclear quadrupolar resonance (NQR) measurement. The bulk superconductivity was found setting in at 0.40K below which the coherence peak was absent thereby suggesting unconventional superconductivity with line-node gap.
