Abstract
Susceptibility, specific heat, and muon spin rotation measurements on high-quality single crystals of have revealed bulk antiferromagnetism with Néel temperature and an ordered moment perpendicular to the 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
