Abstract
Cu nuclear quadrupole resonance (NQR) studies have been carried out for CaCu3Ru4O12, which has been suggested to show a heavy-fermion-like behavior although it possess no f electron. A Lorentzian shape of the Cu NQR line with a narrow width implies that no magnetic ordering appears, at least, down to 5Â K. The spin-lattice relaxation rate of the Cu nuclei probes a change of the Cu 3d electron nature, resulting in the Fermi liquid state at a low temperature. These facts strongly support that the heavy fermion picture is available in the concerned compound.
