In this contribution, we present an investigation of the magnetic and transport properties of La0.75Sr0.25MnO3 (LSMO) /LaNiO3 (LNO) multilayers. LSMO is a ferromagnetic metal below room temperature, and LNO is a paramagnetic metal in all the temperature range studied. We performed a characterization of the magnetic coupling in trilayers of these compounds with different LNO thicknesses by means of magnetization loops and FMR spectroscopy. Transport measurements were carried out in these trilayers in order to study the influence of the magnetic coupling on the transport properties of the system. The samples were patterned by optical lithography in order to perform transport measurements in the CPP configuration (current perpendicular to the films’ plane).
