Abstract

We report magnetoresistivity measurements on a La_1.2Sr _1.8Mn₂O₇ single crystal. The charge transport in the ferromagnetic phase is dominated by two-magnon scattering in the high T range and by weak localization effects at lower T, in the non-metallic regime. In the paramagnetic phase, ρ_ab(T) obeys the adiabatic small polaren hopping mechanism, while ρ_ab(T) follows an Arrhenius behavior with the same activation energy.
