  Single-phase polycrystalline La2MnVO6 samples were synthesized by arc melting
and characterized by X-ray diffraction, magnetization and resistivity
measurements. We find that the compound has cubic (space group), partly ordered
double perovskite structure. The sample exhibits ferrimagnetic behavior and
variable-range hopping conductivity. We conclude based on the magnetic
properties that both Mn and V ions are trivalent; moreover, the Mn3+ ions are
in a high-spin state, which is the reason that the compound is not a
half-metallic antiferromagnet.
