The magnetism of the A-site-ordered perovskite LaMn3V4O12 is studied comprehensively by means of neutron powder diffraction experiments and theoretical calculations. Magnetic neutron diffraction results show that a rhombohedral 60 degrees spin structure emerges on the cubic lattice below a 44-K Neel transition. Ab initio electronic structure calculations confirm that high-spin Mn2+ moments are localized while V 3d-band states are itinerant, and that the noncollinear 60 degrees spin structure is more stable than collinear ferromagnetic or G-type antiferromagnetic alternatives. Effective Heisenberg model calculations reveal that the appearance of such a nontrivial spin structure can be attributed to significant next-nearest-neighbor and third-nearest-neighbor magnetic interactions.
