Abstract

The Alk_1-xRe_xMnO₃ manganites, where Alk=Sr, Ca, Ba and Re=rare earth, are very well known as magnetoresistive materials near room temperature. The substitution of Mn with other transition cations produce a change of Mn-O-Mn interactions, followed by corresponding change in the electronic phase diagram. The samples La_0.54Sm_0.11Ca_0.35Mn_1-xCuxO₃ (LSCMCO) nominal composition thick films were prepared by spin-coating deposition method on Al₂O₃. We have discussed the dependence of the transition from the metal to insulator behavior and the modification of FM/AFM concentrations for each active element composition of sensor.
