Lamellar A<sub><i>x</i></sub>CoO<sub>2</sub> cobalt double oxides with A = Li, Na, and K (<i>x</i> 0.6) have been synthesized and their chemical (alkali content, oxidation state, and structure) and physical (resistivity, thermopower, magnetization, and specific heat) properties have been studied. All the three materials exhibit strong electron correlation emphasized by their behavior ranging from Fermi liquid to spin-polarized system. Our results show that both the dimensionality of the interactions and the nature of the alkali play a determining role on the properties.< Réduire
