Abstract Charge ordering in doped CoO 2 planes near the commensurate fillings x = 1 4 and 1 3 are considered for Na x CoO 2  ·  y H 2 O and suggested to be competitors to superconductivity, leading to the experimentally seen narrow superconducting dome bounded by commensurate doping: 1 4 x 1 3 . Intercalated hydrogen bonded H 2 O network, by its enhanced dielectric constant, screen and frustrate local charge order condensation energy and replace a generic ‘charge glass order’ by… Expand

Charge and spin orderings in triangular t-J-V model with quarter filling: application to Na(0.5)CoO(2).
It is found that the charge ordering (CO) and spin ordering arising from the spin exchange interaction J competes with that from the inter-site Coulomb interaction V, and the stable GS is insulating with striped CO and antiferromagnetic ordering, avoiding the homogeneous frustrated phase. Expand
