Epitaxial manganite thin films with very high room temperature magnetoresistance (MR) values are designed by tuning several parameters as composition, microstructure, substrate material, and film thickness, simultaneously. The resulting La 0.7 Ca 0.2 Ba 0.1 MnO 3 /Ag composite thin films deposited on (111) SrTiO 3 have room temperature MR values exceeding 75% under 7 T applied magnetic field. The opportunity to develop materials out of the manganite family for specific conditions and applications by simultaneous adjustment of several degrees of freedom is successfully demonstrated.
