Resumen:
We have studied the transport and magnetic properties of strongly textured metal/insulator La1xSrxMnO3 ðx ¼1xSrxMnO3 ðx ¼
0:4; 0:1Þ 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 metalinsulator transition around Tc (B250 K) and colossal magnetoresistance which is
maximum around Tc: 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.:4; 0:1Þ bilayers and trilayers, grown by DC magnetron sputtering over MgO and SrTiO3 substrates. The multilayers
