Nonadiabatic small polarons, positive magnetoresistance, and ferrimagnetism behavior in the partially inverse Mn2-xV1+xO4 spinels

We present experimental results of electrical resistivity (ρ), magnetoresistance (MR), Seebeck coefficient (S), and magnetic susceptibility () experiments at high temperature on the spinel Mn2-xV 1+xO4 series with x=0, 1/ 3, and 1, prepared by solid state reaction. The Rietveld analysis of neutron p...
