| Description | Journal: Materials Research Express $CaCu_{3}Ru_{4}O_{12}$ is a Pauli paramagnetic metal oxide consisting of both 3d and 4d magnetic ions in a Cubic-perovskite crystal structure. This present work probes a change in magnetic ground state with the influence of Co. Polycrystalline $CaCu_{3}Ru_{4-x}Co_{x}O_{12}$ (0 ≤ x ≤ 0.1) powder samples have been prepared by conventional solid state reaction under ambient condition. X-ray photoelectron spectroscopy suggests the formation of $Cu^{3+}$ and $Co^{3+}$ ions. The absence of electron paramagnetic resonance (EPR) signal for x = 0.1 also confirms the presence of low spin Cu$ ^{3+}$ in doped system. Partial replacement of $Ru^{4+}$ by $Co^{3+}$ leads to a transition from itinerant Pauli to localized paramagnetism. Resistivity follows Fermi liquid behavior at low temperature. |
