N2 - We investigated magnetic domain structures in granular La 0:6Sr0:4MnO3 thin films using magnetic force microscopy (MFM) at 78 K. Scanning-mode atomic force microscopy (AFM) resolved individual grains ̃50nm in diameter, while MFM imaged perpendicular magnetic domains. The magnetic field distribution gradually inverted across the magnetic domain boundaries, and the width of the transition region reached ̃250 nm. We postulate that the grains behave as single domains with either in- or out-of-plane magnetization and that in-plane domains are stabilized near the magnetic domain boundaries.
