Abstract

Susceptibility, specific heat, and muon spin rotation measurements on high-quality single crystals of Na0.82CoO2 have revealed bulk antiferromagnetism with Néel temperature TN=19.8±0.1K and an ordered moment perpendicular to the CoO2 layers. The magnetic order encompasses nearly 100% of the crystal volume. The susceptibility exhibits a broad peak around 30 K, characteristic of two-dimensional antiferromagnetic fluctuations. The in-plane resistivity is metallic at high temperatures and exhibits a minimum at TN.
