N2 - The electrical resistivity and low-temperature specific heat of exchange-enhanced Pauli paramagnetic Laves phase quasi-binary compounds Lu(Co1-xMx)2 (M = Al, Ga and Si) have been investigated in order to discuss the spin fluctuation characteristics and the Kadowaki-Woods plot. In these three kinds of quasi-binary system, both the electrical resistivity coefficient A and the specific heat coefficient γtot at low temperatures decrease at first and then significantly increase with increasing x. The concentration dependence of magnetic susceptibility at 0 K, χX(0). is also similar to that of A and γtot. The Wilson ratio becomes very large because of the enhancement of magnetic susceptibility. The Kadowaki-Woods plot is fitted to the same universal line of heavy-fermion compounds, A15-type Nb3Sn and V3Si compounds because of significant spin fluctuations in the present quasi-binary compound systems.
