AB  - Specific heat of layered NaxCoO2 (x=0.65, 0.70, and 0.75) oxides has been measured in the temperature range of 3-360 K and magnetic fields of 0 and 9 T. The analysis of data, assuming the combined effect of interlayer superexchange and the phase separation into mesoscopic magnetic domains with localized spins embedded in a matrix with an itinerant electronic character, suggests that the dominant contribution to the specific heat in the region of short-range ordering is mediated by quasi-two-dimensional antiferromagnetic clusters, perpendicular to the CoO2 layers.

AB  - Specific heat of the layered Na0.65CoO2 powder sample over the temperature region of 3-360 K has been studied. Features hinting at charge ordering below room-temperature were observed. Magnetic phase transition at 28 K as well as signs of short-range ordering confirm the 2D character of magnetism with weak inter-planar coupling in the system. Comparison to different 2D antiferromagnetic models suggests that the magnetic lattice is more square- than triangular-like, what could be favoured by the charge ordering.
