  Abstract We have studied the transport and magnetic properties of strongly textured metal/insulator La1-xSrxMnO3 (x = 0.4, 0.1) bilayers and trilayers, grown by DC magnetron sputtering over MgO and SrTiO3 substrates. The multilayers present transport properties similar to those of the La0.6Sr0.4MnO3 films, being very sensitive to deposition conditions. Magnetic multilayers show a metal-insulator transition around T-c (similar to250 K) and colossal magnetoresistance which is maximum around T-c. No extrinsic magnetoresistance associated with the multilayered structure was observed, probably due to the presence of ferromagnetic coupling between the metallic layers, as suggested by magnetization measurements.
