| dc.description.abstractEn | The layered P2-K4Co7O14 oxide has been prepared and characterized by means of X-ray diffraction, electrical conductivity, thermopower, and magnetic measurements. The crystal structure of K4Co7O14 (P63/m space group, Z = 2, a = 7.5171(1) Å, and c = 12.371(1) Å) consists of a stacking of slabs of edge-shared CoO6 octahedra with K+ ions occupying ordered positions in the interslab space, leading to a a0V7×a0V7 supercell. Potential energy calculations at 0 K are ivn good agreement with the ordered distribution of potassium ions in the (ab) plane. This oxide is metallic, and the magnetic susceptibility is of Pauli-type, which contrasts with the Curie-Weiss behavior of the homologous NaxCoO2 (x~0.6) oxide with close alkali content... | |
