"The layered cobaltate La0.30CoO2 was prepared from NaxCoO2 precursor by a solid-state ionic exchange and was characterized by means of X-ray and neutron diffraction,magnetic,thermalandelectric transport measurements.The compound consists of hexagonal sheets of edge-sharing CoO6 octahedra interleaved by lanthanum monolayers.Compared to Na+ in the parent system,the La3+ ions occupy only one-third of available sites,forming a 2 dimensional superstructure.The deviation from the ideal stoichiometry La1/3CoO2 introduces extra hole carriers into the diamagnetic LS Co3+ matrix making the sample Pauli paramagnetic.The temperature dependence of the electrical conductivity in La0.30CoO2 follows Mott\u00B4s T-1/3 law up to about 400K,which is in contrast with the standard metallic behavior in the Na+ homolog possessing the same formal doping.The experiments are complemented by electronic structure calculations for La0.30CoO2 and related NaxCoO2 systems."@en .
