Temperature-dependent resistivity of CaCu3Ru4O12 single crystal #1, single crystal #2, and polycrystal from 2 K to 300 K. The electrical current is along the [100] direction for single crystal #1 and 2#. The left inset shows the resistivity of single crystal CaCu3Ru4O12 #1, #2 versus T 2 below 30 K, and the right inset shows that of polycrystalline CaCu3Ru4O12 versus T 2 below 30 K. The solid lines represent fitting data to ρ = ρ 0+ AT 2.
