Incommensurate Mn spin order has been discovered in the perovskite MnVO3 containing localized 3d(5) Mn2+ and itinerant 3d(1) V4+ states. This phase has a distorted Pnma crystal structure (a = 5.2741(6) angstrom, b = 7.4100(11) angstrom, and c = 5.1184(8) angstrom at 300 K) and is metallic at temperatures of 2-300 K and at pressures of up to 67 kbar. Neutron scattering reveals a (0.29 0 0) magnetic vector below the 46 K spin ordering transition, and both helical and spin density wave orderings are consistent with the diffraction intensities. Electronic structure calculations show large exchange splittings of the Mn and V 3d bands, and (k(x) 0 0) crossings of the Fermi energy by spin up and down V 3d bands may give rise to Ruderman-Kittel-Kasuya-Yosida coupling of Mn moments, in addition to their superexchange interactions.
