Abstract

We report on the magnetic and transport properties of thin films of La_0.67Ca_0.33MnO₃ as a function of annealing temperature, substrate material and film thickness. The films were sputtered from a stoichiometric target with the same nominal composition and were grown epitaxially on SrTiO₃ and LaAlO₃ substrates. We find a clear correlation between the ferromagnetic ordering temperature T_M and the magnitude of the magnetoresistance ratio (MR ratio). Also, T_M appears to be extremely sensitive to the preparation conditions: within the one composition investigated, T_M could be made to vary between 125 K and 255 K.
