Abstract
The precursor samarium nickelate or samarium-neodimium nickelate films were fabricated by a spin coating method using Sm-Ni or Nd-Sm-Ni aqueous solutions, and SmNiO3 and Nd0.5Sm0.5NiO3 films were obtained by heat-treatment of the precursor films at 750 °C in oxygen atmosphere. The resulting SmNiO3 and Nd0.5Sm0.5NiO3 films showed an electrical transition with the transition temperatures of 124.0 and 32.5 °C, respectively. Both of the films showed optical thermochromic properties at the above mentioned transition temperatures.
