Abstract
We report calorimetric, magnetic and electric transport properties of single-crystal CaRuO3 and SrRuO3 as a function of temperature TT and applied magnetic field BB. We find that CaRuO3 is a non-Fermi-liquid metal near a magnetic instability, as characterized by the following properties: (1) the heat capacity C(T,B)∼−TlogTC(T,B)∼−TlogT is readily enhanced in low applied fields, and exhibits a Schottky peak at 2.3 K that exhibits field dependence when TT is reduced; (2) the magnetic susceptibility diverges as T−γT−γ at low temperatures with 1/2<γ<11/2<γ<1, depending on the applied field; and (3) the electrical resistivity exhibits a T3/2T3/2 dependence over the range 1.7
