Doping-independent 120° magnetism in the quadruple perovskite CaMn3V4O12
Résumé
The magnetic structure of high-pressure quadruple perovskite CaMn3V4O12 was investigated using neutron powder diffraction data. Below TN=54K, the S=52 Mn2+ spins adopt a 120∘ arrangement in kagome layers formed of second nearest neighbor A′ sites. The V4+ electrons are itinerant and do not mediate the magnetic interactions as evidenced by the insensitivity of the magnetic structure to the valence of the vanadium cations in AMn3V4O12 (A=La3+, Ca2+).
