Paper Abstract

The Alk1-xRexMnO3 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 La0.54Sm0.11Ca0.35Mn1-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.
