abstract = {Perovskite-type LaVO2.78N0.10 powder was synthesized by
thermal ammonolysis of the oxide precursor LaVO4. By X-ray,
neutron, and electron diffraction an orthorhombic crystal
structure with space group Pnma was identified. XANES
spectra showed that the oxidation state of vanadium changes
from 5+ in LaVO4 to approximately 3+ in LaVO2.78N0.10. The
temperature dependence of the electrical conductivity
revealed an Arrhenius-type behavior with an activation
energy of 0.103 eV in the temperature range of 119–302 K
indicating that the conduction process is thermally
activated band transition. Based on the positive Seebeck
coefficient, holes were identified as the dominant charge
carriers in the temperature range of 100–302 K. Both the
Seebeck coefficient and the thermal conductivity showed an
anomaly at 138 K, which is attributed to the Néel
temperature for antiferromagnetic ordering according to
magnetic susceptibility measurements.},
