The electronic and magnetic properties of La3RuO7have been investigated. Its structure consists of corner-sharing RuO6octahedra arranged in one-dimensional chains with a Ru-O-Ru angle of 145°. The magnetic susceptibility shows Curie-Weiss behavior at 50–400 K with θ=-14K and an effective moment of 3.94 μ B/Ru atom. At lower temperatures (20–50 K), short-range antiferromagnetic order is observed. Neutron diffraction and magnetic susceptibility data show that long-range antiferromagnetic order exists below 20 K. A spin-flop transition is observed at applied fields greater than 1 T and temperatures below 17 K. Band structure calculations predict anisotropic electronic behavior and show that the ground state should be antiferromagnetic.
