Abstract

We report a magnetic transition region in La0.7Sr0.3MnO3 with gradually changing magnitude of magnetization, but no rotation, stable at all temperatures below TC. Spatially resolved magnetization, composition and Mn valence data reveal that the magnetic transition region is induced by a subtle Mn composition change, leading to charge transfer at the interface due to carrier diffusion and drift. The electrostatic shaping of the magnetic transition region is mediated by the Mn valence, which affects both magnetization by Mn3+-Mn4+ double exchange interaction and free carrier concentration.
